 * I have been getting this error message in my Apache server error log for a good
   while now and I’ve just upgraded CKEditor and am still getting it.
 * PHP Fatal error: Call to undefined function _e() in /path/to/wp-content/plugins/
   ckeditor-for-wordpress/includes/upload.php
 * or
 * PHP Fatal error: Call to undefined function _e() in /path/to/wp-content/plugins/
   ckeditor-for-wordpress/includes/basic.php
 * Anyone else experienced this or got any ideas as to what is causing it and perhaps
   how to fix it?
 * Thank you

 * Hi, it looks like problem with your wordpress installation.
    Function _e is used
   in wordpress to translations ([http://codex.wordpress.org/Translating_WordPress](http://codex.wordpress.org/Translating_WordPress)).
   It looks like it is not exists in you wordpress. What theme do you use ? What
   plugins do you have installed ?

 * FYI, Since it’s appearing in the apache error logs, it probably means that a 
   search engine is loading the file directly, or an automated exploit scanning 
   bot is probing files looking for an exploitable filed. Access the file directly(
   ie [http://…/wp-content/plugins/ckeditor-for-wordpress/includes/upload.php](http://…/wp-content/plugins/ckeditor-for-wordpress/includes/upload.php))
   and you’ll probably duplicate the message.
 * ie. your site is probably one of the 3,000 sites listed [ in this google search](http://www.google.com.au/search?q=inurl:%22ckeditor-for-wordpress/includes/upload.php%22)

 * Thx for that information. Yes I know that in most wordpress installations users
   can list wordpress (plugins also) directories and this also works with search
   engines – they can index wordpress subdirectories. I think that such things should
   be done by wordpress (so only necessary files should be visible).
