Calendar keeps on loading

[Ronja Nassenstein]

Hello,

I have a problem with the calendar on my page. Although it worked within the past half year, the calendar itself is being displayed but now keeps on loading and does not show any event.

On Github I read that it could be an AJAX response mistake. What I tried so far was deactivating all other plugins and reinstalling the Event Organiser Plugin. I also deleted all (via iCal Extension) automatically imported events and created a single one manually. But unfortunately none of that works. In the browsers developer tools in debug mode I found one mistake.(“Failed to load resource: the server responded with a status of 500 (Internal Server Error)”) Unfortunately I am unable to detect the cause of the problem and I also don’t know how to fix it.

This is the link to my site: http://www.mv-dohrgaul.de/calendartest/

Could you please have a look and see what may cause the problem?

Thanks in advance,

Ronja

Hi Donna,

A 500 error means there was an error in the code being executed on the server side. That error is preventing the server from responding to the request.

Are you able to check your error logs. (These are time-stamped so you may want to reproduce the error and look up the error message on the error logs).

If you’re not sure where your error logs are you can enable WP_DEBUG and WP_DEBUG_LOG in your wp-config.php (see https://codex.wordpress.org/Debugging_in_WordPress). Any subsequent errors should then be written to wp-content/debug.log

Thanks for your reply, Stephen.

I had a look at the error logs. See text below:

I don’t know how to solve the issue. Do you have any idea?

Hi Ronja,

The event query isn’t returning an occurrence ID for the event. This can only really be the case if a plug-in / theme is interfering with the query. There are some debugging steps we can take to better understand the problem, but first have you tried switching to a Twenty<Something> theme?

[Ronja Nassenstein]

Hi Stephen,

I found the mistake thanks to your proposal to change the theme. It seems as if our theme “Impreza” is no longer working in accordance with the calendar. Another theme works very fine.

Thank you very much for your help!
