 * I have installed this plug in on a WordPress 4.5.1.
 * The one on [http://www.fagerland.me](http://www.fagerland.me) works fine but 
   with [http://www.sommerbyensandnes.no](http://www.sommerbyensandnes.no) I get
   the following error:
 * —
    Internal Server Error
 * The server encountered an internal error or misconfiguration and was unable to
   complete your request.
 * Please contact the server administrator, [support@one.com](https://wordpress.org/support/topic/internal-server-error-412/support@one.com?output_format=md)
   and inform them of the time the error occurred, and anything you might have done
   that may have caused the error.
 * More information about this error may be available in the server error log.
    —
 * Any ideas why?

 * Getting the same problem. Anyone else have this or find a solution?

 * hallrar,
    Your calendar is working now–what did you do to solve the problem??
 * We have been having the same problem. No luck figuring out the root problem, 
   and no response from developers. I can’t even export the events to a different
   plugin because the calendar page is not working.

 * Try changing the PHP version to 5.6.
 * Yes, I am also a little worried there is no help from the developer here.

 * We were already using 5.6. Switched back to 5.4 to see if that helped. +/-CGI
   doesn’t make a difference, either. There are a few additional tools that were
   automatically installed during the version change, I discovered, and I’m trying
   to figure out if one of them is causing problems. I’ve had errors related to 
   Zend OPcache and Zend Engine API, but no idea if those are related to this plugin.
   Would be great if the company paid attention to how many people are having problems,
   but they’re clearly focused on selling and supporting their other products.
