# Cron errors & media library blank

 * After updating the plugin, I’m now getting the following error on every page 
   of my site:
 *     ```
       Warning: Cannot unset offset in a non-array variable in /*****/wp-includes/cron.php on line 151
       Warning: Cannot unset offset in a non-array variable in /*****/wp-includes/cron.php on line 153
       ```
   
 * Even when I deactivate the plugin, I still get this error. My media library is
   also showing up blank. I haven’t changed anything else, and since the plugin 
   update changed how cron jobs are run I can’t help but feel like there’s some 
   connection. I’ve tried replacing all the WP core files but nothing seems to make
   this error go away.
 * Thank you!

 * Hm, I guess the media library problem was just because of the error. If I hide
   the error, the media library works again. But is the error itself something to
   worry about?

 * It is just a warning created for the cron.php as it is not getting the appropriate
   variables.
    You can comment it out or else get back the wp-includes from a fresh
   setup.

 * I replaced the whole wp-includes folder and the error was still there. Does the
   fact that it’s not getting the appropriate variables cause a problem? By comment
   it out do you mean the function triggering the error?

 * I’ve also noticed that iThemes Security is no longer updating my .htaccess, even
   though I have it set to. Before this update it always worked, and suddenly now
   it doesn’t. Any idea why this would be?

 * I never figured out exactly what was causing it, but the only fix was completely
   trashing iThemes Security and switching to a different plugin.
