 * I just enabled LiteSpeed plugin and I can’t access admin pages! I can’t figure
   out how to disable this either. I’ve removed the .htaccess changes.
 * The [http://www.aadallas.org](http://www.aadallas.org) page isn’t working
 * [http://www.aadallas.org](http://www.aadallas.org) is currently unable to handle
   this request.
    HTTP ERROR 500

 * Ok, I tried the “rename the plugins directory method” and now I’m getting 500
   for all pages, even when I renamed the plugins directory back!

 * Hi [@laurin1](https://wordpress.org/support/users/laurin1/)
 * If you are able to access the file system, are there any error_log files in the
   admin directory?
 * Thanks,
    Kevin

   you Thank you Thank you
 * My wp-config.php file was all jacked up (had serious syntax errors). How could
   a plugin do that???

 * Glad to hear that you were able to resolve it. It’s possible that there were 
   some writes to the file that may have re-ordered it?
 * What did you see that was changed?
 * Our plugin does the following:
    1. If the WP_CACHE define is already set, do 
   not change anything. 2. If the wp-config file is not writable, return an error.
   3. If there is a define WP_CACHE false, set it to true. 4. If (3) does not exist,
   Look for table_prefix and add a define before that. 5. If (4) does not exist,
   try to add to the start of the file after <?php 6. if (5) fails, return error
 * Do you know what case you had? So we could see if something happened because 
   of the cache plugin.

 * Here is what was broken, this is lines 1-4 of wp-config.php:
 *     ```
       <?php
   
       global define('WP_CACHE', true);
       $table_prefix;
       ```
   
 * For some reason, it stuck “define(‘WP_CACHE’, true);” between global and $table_prefix.
   I added the global $table_prefix (because PHPStorm throws a warning if I don’t
   have that and it’s just a good reminder).

 * Thanks for that!
 * That explains everything actually. We specifically add it before $table_prefix,
   and did not search for the beginning of the line. We’ll work on a fix for this
   situation, so it doesn’t happen again.
 * Thanks again!
