Running Core 2.7...
After installing the Grid fieldtype, I can no longer add or edit any channel fields. Upon attempting to save changes, I am simply redirected to a status 404 page. Debugging is turned on, but everything is simply blank. Screenshot is attached.
I have only one additional fieldtype installed - Expresso. I don’t want to uninstall yet as most of the site’s content is dependent on this fieldtype.
Has anyone else encountered this problem? I found a few threads here on the forums but they are locked in the Developer Preview subsection….
Any suggestions on how to troubleshoot? Thanks!
