Cannot Add Any Items to Exhibit

I wonder if there is a limit of items that I can add to an exhibit. As of today, I cannot add any more items to our largest exhibit (both gallery and geolocation map). The following error occurs: “There was an error on the form. Please try again.”
For our smaller exhibits, I can still add items.

Thank you for your support!

How big is this exhibit?

There’s not a limit built into Omeka itself, but I think you’re probably seeing a limit that comes from PHP.

There’s a php.ini setting called max_input_vars that limits how many individual pieces of data you can submit from one form; on the exhibit edit page each new attachment, block, etc. will add to this count. You can increase the limit by editing your php.ini file.

Thank you, I could locate the file and change the setting!
