Error when uploading items

Hello. We are new to Omeka-S and are trying to add items. When I click “items” in the Admin dashboard and under resources I receive the following error message:

“This page isn’t working
omeka.humboldt.edu is currently unable to handle this request.
HTTP ERROR 500”

We have updated to Omeka - S v1.0.0-beta4. Is this a known problem, or do you have recommendations on how to troubleshoot this issues? Thank you! Carly

Could you enable the error log and show it (in the .htaccess file of your install, set temporarily SetEnv APPLICATION_ENV "development" instead of production)?

Thank you! Here is the error I now see:

Fatal error: Call to undefined method Omeka\Entity\Item::id() in /var/www/html/omeka-s/modules/Mapping/Module.php on line 207

I really appreciate your help.

Carly

Yeah, I encountered the same problem.

You should disable the Mapping module and/or install the last update. This bug seems have been fixed in Mapping 1.0.0-beta3.
