 * We got today another warning and error in our PHP logs:
 * Warning: implode(): Invalid arguments passed in /home/xxx/public_html/wp-content/
   plugins/404-solution/includes/Functions.php on line 50
 * and
 * Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate
   20480 bytes) in /home/xxx/public_html/wp-content/plugins/404-solution/includes/

 * Sorry, it is all deleted now but I think there was none. However, maybe it is
   connected to the other error I have written. That scheduled posts…

 * Okay. I’ve included more debug information in version 2.20.3 so I can see what
   might be causing the implode() issue. I should start getting the automatic emails
   from people participating in the “help the author by emailing the log file” within
   the next few days. Then hopefully I’ll have enough information to fix the issue.

 * This should be fixed with version 2.21.3
