 * Hi. Thank you for creating the plugin. I can install it OK, but when I go to 
   activate it, the system crashes and throws a 500 Internal Server Error. There
   are no other plugins active on the site.
 * I tried it twice and both times it crashed – each time I have to SSH to the server
   and rename the plugin, then I could access the site again.
 * Any ideas?
 * Thanks
 * Mike

 * Hi [@mklaphek](https://wordpress.org/support/users/mklaphek/) could you provide
   some details about your setup ? WP version, PHP version.

 * Hi. The WordPress version is Version 4.8.2; PHP Version is PHP/5.5.9-1ubuntu4.22.
 * Thanks for the help. BTW, we went another way, so we’re not using the plugin,
   but it would be nice to know why we got the error.

 * [@mklaphek](https://wordpress.org/support/users/mklaphek/) thank you for the 
   details, I will look into that as soon as I have some capacity. Busy with my 
   full-time job, but please keep me posted if you figure out this yourself.
