HTTP 500 Error When Editing Events

Hello. We’re having a consistent problem when attempting to edit events within Event Espresso. We’re running WordPress 5.1.1 and Event Espresso 4.9.79.

In the Dashboard we select Event Espresso > Events and the “edit” an individual event. Editing any field and then attempting to publish that updated information will result in the Http 500 error and the updates will not publish.

We placed tickets with the ISP for server review and everything has checked out on that side of the equation. Rebooting webserver, database, refreshing the php version… no changes.

We’d appreciate your input

Hi there,

Error 500 is a catch-all error displayed to visitors rather than the full error.

To know what the problem is here we’ll need the full error and you can usually find that in the error logs for your server. Does your host have a section where you can view error in your control panel? If so, trigger the error then visit the error log, do you see an error there?

If not, you can check with your host and ask them if they can see the error on the server, or add the snippet of code herre:

To your wp-config.php file in places of just define( 'WP_DEBUG', false ); (which is usually included in that file by default).

We did receive your request for priority support, but I’m afraid the FTP connection times out. Can you double check the FTP settings and verify that it allows an FTP client to connect?

We’ll need FTP access to switch on DEBUG mode.

Hmmm, that’s odd, it was working for me a short while ago. In the meantime I think our development team may have discovered something so could we hold off on the priority support token? For the first time this morning EventEspresso was showing an error before the HTTP500 error screen took over.

“The maximum number of inputs on this page has been exceeded. You cannot
make edits to this page because of your server’s PHP “max_input_vars”
setting. There are 3831 inputs and the maximum amount currently allowed by your server is 1000. Please contact your web host and ask them to raise the “max_input_vars” limit.”

We’re having the ISP reset the PHP input var level and will test again further and post an update. If that clears it, great. If not we’ll proceed further

It appears that this has resolved the issue. Editing all day without any further Http 500 errors. We can close this support item. Thank you.
