Word Press have missed schedule issue from 2.7 version onwards. Word Press post scheduling was working fine upto   2.6.5 version as many of users reported on web.  You can schedule wordpress post to publish on a specified time. but when time comes post can not publish and shows missed schedule in the admin area.  According to WP guys, this is not the issue that Word Press guys can fix. This issue comes when your web server can not properly execute wp-cron process.  New wordpress wp-cron method run wp-cron in separate process that rely on web server configuration. Everytime Word Press loads it looks for wp-cron whether it should be run or not based on the time it was last run.

Here are some reason that prevent Word Press to run wp-cron correctly.

• Server doesn’t have DNS, and so it can’t figure out who “example.com” is, even though it is *itself*.
• Server administrators, in a misguided attempt at security, have blocked “loopback” requests, so it can’t actually make a call back to itself.
• Server is running something called “mod_security” or similar, which actively blocks the call due to brain-dead configuration.

There is simple to complex workaround to solve this issue. This problem automatically fix when your server is configured to run wp-cron properly but it require server root access and extensive server administration knowledge. So server configuration method is simply not for everyone to use. There is simple workaround to fix this issue that force wordpress to run wp-cron using alternative method that does not rely on web server configuration. To fix the issue add below line in the wp-config.php file. This line can be add anywhere in the wp-config.php file.

define(‘ALTERNATE_WP_CRON’, true);

This should restore wordpress schedule functionality.

1&1 Linux hosting still support PHP4 as default php processor for .php files. To run PHP5 you need to rename .php file as .php5 file. But it is hard to rename all application files at once. You can use PHP5 in your account by following simple steps below:

• Create a .htaccess file or edit .htaccess file if you application already using
• Add below lines on the top on file content
  AddType x-mapp-php5 .php
  AddHandler x-mapp-php5 .php
• Upload .htaccess file to root folder of your hosting account.

Screenshots

I recently encounter this issue on my client wordpress mu blog.  When i open main blog page after installation an infinite loop occur and stop at dead end in Firefox. I searched a lot about this on wordpress forum. Surprising, issue is stated everywhere in the forums and blog but no solution was suggested.

Why Redirect Loop?

The issue arise because database was not created during wordpress installation but word press config file was written. WordPress uses wp-config.php file to store database configuration.  If WordPress find this file in the  installation directory then no further installation procedure begin. WordPress now look at DB to load default blog but there is no table in the database. Again, control goes to install procedure but WordPress understand blog already installed because WordPress config file is present in root folder. Once again WordPress try to load blog from database and redirect loop occur.  I hope WordPress guys will fix this in future releases.

The Fix

The fix is very simple. Simply, rename or delete WordPress config file and re-install wordpress mu.  Make sure database user you are using during installation have sufficient permission to create and manipulate database tables.

Today, i  discovered that my blog feed was showing error in Firefox and other browsers.  This error comes if white space of empty line at the start of xml feed content. Your xml feed content should start with xml declaration without white space or empty line. Blank lines or white space can be introduced by theme code, plugins, wordpress code or wordpress configuration file. A quick fix is check files you have recently edited.

How to Fix

• Deactivate all plug-ins loaded and activate plug-in one by one to catch exact plug-in creating problem.
• Try disabling wordpress cache plug-ins. Wordpress cache plugin don’t work well with some hosting.
• Check your theme files, wp-config.php file for blank lines. It is hard and time consuming to check all wordpress core files. Thanks yo fiyaga for usefull wordpress plugin “Fix RSS Feed” that automatically detect blank or white space in the wordpress core files.
• Make sure to ping your feed in feedburner or similar service you are using.

I just received “Not Acceptable Error while i tried to edit post in Word Press 2.5. Earlier, It was working fine but in the previous post i get annoying error when i tried to save and continue my article. But soon i realize cause of the error. Again, the error was due to apache web server mod-security rules SecFilterEngine On. The exact text of the error is “Error 406, Not Acceptable. An appropriate representation of the requested resource /wp-admin/post.php could not be found on this server.”

Here is the quick fix the error:

1. Download .htaccess file from your root directory or create one if not exist.
2. Add following Line in .htaccess file.
3. <IfModule mod_security.c>
   <Files post.php>
   SecFilterEngine Off
   SecFilterScanPOST Off
   </Files>
   </IfModule>
4. If <IfModule mod_security.c> line already in your .htaccess file then place only <Files..></Files> block inside if module block.
5. Save file and upload file to your host root directory.
6. All done..

This is the most recent error i have found after upgrade to wordpress 2.5. Wordpress 2.5 uses extremely new way to handle images but most of user found problem in image upload due to apache mod_security module. The file responsible for image upload is async-upload.php in wp-admin folder. you may encounter following error message while uploading images to wordpress;

• HTTP error
• An error occurred in the upload. Please try again later.

This is the default message for image upload error. It should be more description and problem oriented so that user can determine problem easily. However most of the wordpress user face this error due apache mod_security filter enable for the website. To fix the problem you need to turn off apache mod_security filter for the async-upload.php file. The fix is very simple, you just need to update .htaccess for this.

Soution:

1. 1) Use any free ftp program or you control panel file manager to download special file called .htaccess
2. Edit file in your favourite text editor.
3. You will find following content in file if you havn’t applied any custom htaccess rules.
   

   Options All -Indexes
   <IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteBase /
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule . /index.php [L]
   </IfModule>

4. Add following line at the end of the file. Don’t worry if you have not above content in file or you didn’t find file at your host root. Create new file .htaccess with the below content.
   

   <IfModule mod_security.c>
   <Files async-upload.php>
   SecFilterEngine Off
   SecFilterScanPOST Off
   </Files>
   </IfModule>

5. Now, your file content will look like this..
   

   Options All -Indexes
   <IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteBase /
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule . /index.php [L]
   </IfModule>
   <IfModule mod_security.c>
   <Files async-upload.php>
   SecFilterEngine Off
   SecFilterScanPOST Off
   </Files>
   </IfModule>

6. Just save file and re-upload at the root of your website folder.
7. All done.. Now error must be gone..
