Fix Null error in WordPress comment reply with wordpress-threaded-comments plugin enabled

Friday, April 6th, 2012

I'm running WordPress for already 3 years or so now. Since some very long time. The first wordpress install, I can hardly remember but it something like wordpress 2.5 or wordpress 2.4

Since quite a long time my wordpress blog is powered by a number of plugins, which I regularly update, whenever new plugins pops up …
I haven't noticed most of the time problems during major WordPress platform updates or the update of the installed extensions. However, today while I tried to reply back to one of my blog comments, I've been shocked that, I couldn't.
Pointing at the the Comment Reply box and typing inside was impossible and a null message was stayed filled in the form:

To catch what was causing this weird misbehaving with the reply comments functionality, I grepped through my /var/www/blog/wp-content/plugins/* for the movecfm(null,0,1,null):

# cd /var/www/blog/wp-content/plugins
# grep -rli 'movecfm(null,0,1,null)' */*.php
wordpress-thread-comment/wp-thread-comment.php

I've taken the string movecfm(null,0,1,null) from the browser page source in in my Firefox by pressing – Ctrl+U).

Once I knew of the problem, I first tried commenting the occurances of the null fields in wp-thread-comment.php, but as there, were other troubles in commenting this and I was lazy to read the whole code, checked online if some other fellows experienced the same shitty null void javascript error and already someone pointed at a solution. In the few minutes search I was unable to find anyone who reported for this bug, but what I found is some user threads on wordpress.org mentioning since WordPress 2.7+ the wordpress-threaded-comments is obsolete and the functionality provided by the plugin is already provided by default in newer WPinstalls.

Hence in order to enable the threaded comments WordPress (embedded) reply functionality from within the wp-admin panel used:

Settings -> Discussions -> Enable Threaded (nested) comments (Tick)

You see there is also an option to define how many nested comments subcomments, can be placed per comment, the default was 5, but I thought 5 is a bit low so increased it to 10 comments reply possible per comment.

Finally, to prevent the default threaded comments to interfere with the WordPress Threaded Comments plugin, disabled the plugin through menus:

Plugins -> Active -> WordPress Thread Comments (Deactivate)

This solved the weird javascript null "bug" caused by wordpress-threaded-comments once and for all.
Hopefully onwards, my blog readers will not have issues with threaded Reply Comments.

How to show country flag, web browser type and Operating System in WordPress Comments

Wednesday, February 15th, 2012

!!! IMPORTANT UPDATE COMMENT INFO DETECTOR IS NO LONGER SUPPORTED (IS OBSOLETE) AND THE COUNTRY FLAGS AND OPERATING SYSTEM WILL BE NOT SHOWING INSTEAD,

!!!! TO MAKE THE COUNTRY FLAGS AND OS WP FUNCTIONALITY WORK AGAIN YOU WILL NEED TO INSTALL WP-USERAGENT !!!

I've come across a nice WordPress plugin that displays country flag, operating system and web browser used in each of posted comments blog comments.
Its really nice plugin, since it adds some transperancy and colorfulness to each of blog comments 😉
here is a screenshot of my blog with Comments Info Detector "in action":

Example of Comments Info Detector in Action on wordpress blog comments

Comments Info Detector as of time of writting is at stable ver 1.0.5.
The plugin installation and configuration is very easy as with most other WP plugins. To install the plugin;

1. Download and unzip Comments Info Detector

linux:/var/www/blog:# cd wp-content/plugins
linux:/var/www/blog/wp-content/plugins:# wget http://downloads.wordpress.org/plugin/comment-info-detector.zip
...
linux:/var/www/blog/wp-content/plugins:# unzip comment-info-detector.zip
...

Just for the sake of preservation of history, I've made a mirror of comments-info-detector 1.0.5 wp plugin for download here
2. Activate Comment-Info-Detector

To enable the plugin Navigate to;
Plugins -> Inactive -> Comment Info Detector (Activate)

After having enabled the plugin as a last 3rd step it has to be configured.

3. Configure comment-info-detector wp plugin

By default the plugin is disabled. To change it to enabled (configure it) by navigating to:

Settings -> Comments Info Detector

Next a a page will appear with variout fields and web forms, where stuff can be changed. Here almost all of it should be left as it is the only change should be in the drop down menus near the end of the page:

Display Country Flags Automatically (Change No to Yes)
Display Web Browsers and OS Automatically (Change No to Yes

After the two menus are set to "Yes" and pressing on Save Changes the plugin is enabled it will immediately start showing information inside each comment the GeoIP country location flag of the person who commented as well as OS type and Web Browser 🙂

How to turn off telnetd on FreeBSD

Sunday, December 25th, 2011

There is a brand new remote FreeBSD vulnerability in telnetd in all its versions starting from version 7 to 9. It is therefore advisable that the telnet daemon be completely disabled.

To disable telnetd on FreeBSD:

1. Open /etc/inetd.conf

freebsd# vi /etc/inetd.conf

2. Comment out the line

telnet stream tcp nowait root /usr/libexec/telnetd telnetd

e.g.:

#telnet stream tcp nowait root /usr/libexec/telnetd telnetd

3. Restart inetd

freebsd# /etc/rc.d/inetd restart

How rescue unbootable Windows PC, Windows files through files Network copy to remote server shared Folder using Hirens Boot CD

hirens-boot-cd-logo-how-to-rescue-unbootable-pc-with-hirens-bootcd
I'm rescuing some files from one unbootable Windows XP using a livecd with Hirens Boot CD 13

In order to rescue the three NTFS Windows partitions files, I mounted them after booting a Mini Linux from Hirens Boot CD.

Mounting NTFS using Hirens BootCD went quite smoothly to mount the 3 partitions I used cmds:

# mount /dev/sda1 /mnt/sda1
# mount /dev/sda2 /mnt/sda2
# mount /dev/sdb1 /mnt/sdb1

After the three NTFS file partitions are mounted I used smbclient to list all the available Network Shares on the remote Network Samba Shares Server which by the way possessed the NETBIOS name of SERVER 😉

# smbclient -L //SERVER/
Enter root's password:
Domain=[SERVER] OS=[Windows 7 Ultimate 7600] Server=[Windows 7 Ultimate 6.1]

Sharename Type Comment
——— —- ——-
!!!MUSIC Disk
ADMIN$ Disk Remote Admin
C$ Disk Default share
Canon Inkjet S9000 (Copy 2) Printer Canon Inkjet S9000 (Copy 2)
D$ Disk Default share
Domain=[SERVER] OS=[Windows 7 Ultimate 7600] Server=[Windows 7 Ultimate 6.1]
Server Comment
——— ——-
Workgroup Master
——— ——-

Further on to mount the //SERVER/D network samba drive – (the location where I wanted to transfer the files from the above 3 mounted partitions):

# mkdir /mnt/D
# mount //192.168.0.100/D /mnt/D
#

Where the IP 192.168.0.100 is actually the local network IP address of the //SERVER win smb machine.

Afterwards I used mc to copy all the files I needed to rescue from all the 3 above mentioned win partitions to the mounted //SERVER/D

How to change default Comments and No Comments location in WordPress in wordpress default theme

Tuesday, April 5th, 2011

For a number of time I’ve been planning to change my blog comments placement. Until this very day however I’ve kept the default wordpress theme’s Comments button placement.

I realize the default Comments button placement is a bit hard to see and not that much intuitive for the user that enters my blog for a first time.

My first guess was that there might be somewhere a wordpress plugin which will allow me to adjust my comments button placement.
After some research online and a realization that probably there is no such plugin existing yet. I’ve forced myself to tune it up myself.

It was clear to me that in order to change the it will be necessery to edit the WordPress templates files. I’m not a designer and when I hear about templates I usually get scared, however I took the time to take a look at the default wordpress template and find out actually that template modifications is actually rather easier than I thought.

My previous idea was that in order to edit templates you have to be some kind of CSS and HTML guru (which I’m not). Nevertheless it seems that in order to play and adjust in a good way the templates you don’t need ot be a pro.
Even an uneducated fool like myself can easily do almost everything he thinks of throughout few lines of code in the wp templates.

To get back to the major topic thanks God after a bit of review and reading of wordpress.org documentation and some user forums. I’ve figured out that in order to change my Comments placement you need to modify the file:
 

  • blog/wp-content/themes/default/index.php

In index.php find the line starting with:

You will notice within this opened paragraph the php code:

<?php the_tags('Tags: ', ', ', '
'); ?> Posted in <?php the_category(', ') ?>
| <?php edit_post_link('Edit', '', ' | '); ?>
<?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?>

This is the actual default theme php code that makes the wordpress Comments or No Comments that maes the comments appear on the blog.

Now I’ve decided to let this be as it is but add one more Comment button to wordpress on a different location that is more appealing to my blog visitors

After quick evaluation I’ve determined that probably the best location that the Comments button should have is right after the end of the post text

If you think my idea for button placement is appropriate, to set this location for the Comments button, you will have to find the follwoing code in index.php:

<div class="entry">
<?php the_content('Read the rest of this entry »'); ?>
</div>

Right after the end of this code place the following code:

<?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?>
</div>
