 * Hi,
    I am getting the same error as: sergigonza
 * Updated to version 1.5.5 and generates 500 internal server error. Have to rename/
   deactivate the plugin to access the admin area. Running WP 4.9.4 and PHP 5.5.22
 * Advice appreciated. Thanks.

 * Hi [@arinawinkelman](https://wordpress.org/support/users/arinawinkelman/),
 * In the PHP error log on your server, can see you see the message that was for
   the 500 error?
 * Thanks,

 * Hi Scott,
    Where would I find the php error log? I see nothing in the root of
   the website. Arina

 * Hi [@arinawinkelman](https://wordpress.org/support/users/arinawinkelman/),
 * I would recommend contacting your hosting company to find out.

 * Hi Scott,
    Well, contacted the web host who provided the URL for the error log.
   Reading thru it, I only see errors messages ‘near’ your plugin, when it cannot
   find the correct folder (since I renamed the plugin folder). Then, before and
   after that, there are numerous memory errors, particularly related to php sessions.
   The max PHP memory limit is 256Mb, and cannot be increased under the current 
   package. Sigh. So, why loading your plugin triggers the issue, versus the other
   plugins running, I do not know. Arina

 * Hi [@arinawinkelman](https://wordpress.org/support/users/arinawinkelman/),
 * I can’t recreate the problem, so I need to see the exact error message to understand
   the problem. It could be caused by any number of things, related or not related
   to the plugin.
 * I am not sure if PHP is the problem or not. PHP 5.5 is really old and at end 
   of life ([http://php.net/supported-versions.php](http://php.net/supported-versions.php))
   so I wold recommend upgrading anyways.
 * I am going to close this ticket for now, if you have an error message please 
   let me know.
 * Thanks,
    Scott
