Cannot edit site: "The definition for this element could not be located..."

#1

In the past couple of weeks our site has become uneditable. Every element the pages shows the message: “The definition for this element could not be located. You may need to activate a plugin. The type declared for this element is: undefined”.

I have reviewed other articles and tried the following:

  • Updating cornerstone
  • Clearing site and cornerstone caches
  • Checking cornerstone settings > permissions > elements > All Classic Elements (Toggle All Permissions - on)
  • Resaving Permalinks

Nothing has worked so far.

Hello Joel,

Thanks for writing to us.

It seems that you need to increase the PHP memory limit. I would suggest referring to the documentation to learn more about how to increase the PHP memory limit. Alternatively, you can contact your hosting provider to increase the PHP memory limit and then recheck it.

PHP configuration recommended

memory_limit = 512M
upload_max_filesize = 512M
post_max_size = 512M
max_execution_time = 300
max_input_time = 300

Hope it helps
Thanks
