 * Hi **josephmiddleton**,
    There are couple ways to find out what is wrong. First
   one, if you know how to use browser debugging tool like Firebug, you can check
   ajax calls and see which one failes. In case you do not, check your server error
   log. Maybe there are any errors related to WP Error Fix. The last one, please
   make sure that you are not using any HTTP Compression plugins. They usually are
   the cause of a lot of issues.
 *  Let us know the result.

 * I looked at the error.log and this is what it says. Don’t understand there is
   plenty of memory free on the server.
 *     ```
       [20-Nov-2013 04:40:28 UTC] PHP Fatal error:  Allowed memory size of 268435456 bytes exhausted (tried to allocate 64 bytes) in /[server info]/wp-includes/wp-db.php on line 1554

       ```
   
 * Will try it again and read error log…
 * well that may have nothing to do with it–tried running it again and no errors
   but the one that says javascript failed.

 * Though I am not sure what I am looking at in firebug, looked at console, then
   ran the admin button for fix it and there are 2 red lines. I assume this may 
   be something that can help here
 * 1) `_ajax_nonce 072db6eed5
    action ahm sub_action analyze Source action=ahm&sub_action
   =analyze&_ajax_nonce=072db6eed5`
 * 2) `http://[server info]/wp-admin/admin-ajax.php?action=ahm&sub_action=trigger_view&
   _ajax_nonce=072db6eed5&view=patches&_=1384973802617`

 * Well JavaScript application message is triggered because the request to your 
   server failed. And it failed during ajax call.
 * Based on the error, I’m assuming you have 256M Memory allocation for PHP. And
   it is very common for WordPress database core class to exceed that limit. Usually
   it happens where there is some caching or debugging plugin installed. These kind
   of plugins push a huge amount of information to database and that is why PHP 
   dies.
 * WP Error Fix does not deal with database but it there must be some third party
   plugin that causes this error.
 * Would be nice if you could send me an admin login to your website so I can check
   the potential cause of this error.

 * Thank you Joseph for your time and credentials to admin panel.
 * Based on my investigation the problem was in weird file encoding. I have a filling
   that it has something todo with Security Plugin. This plugins has some internal
   caching and version controlling features. But I can’t confirm this information.
 * The solution is – try to reinstall the WP Error Fix. Deactivate, and Remove and
   download it from WordPress Repository again.

    Vasyl
