I am hoping that someone can help me. I run a network of Drupal websites. They share the same code, but have different databases for each website.
This week, one of the websites began having a serious error -- any user other than me (UID #1) is restricted from seeing all of the content types and therefore cannot add any content, at all.
I've not made any changes to the websites that I am aware of that would cause this to occur. My other websites are all working fine and not having any similar issues.
As UID#1, I can do things normally, but if I masquerade as any other role or user, I am unable to add any content at all. When I mask as one of my higher level users who can see the content types, they are shown a screen that says no custom content types have been created.
I have looked at permissions and everything looks fine. Nothing looks any different than my other websites. I rebuilt the content access permissions and cleared the cache, but that did not help.
I've done some googling to see if I could find any similar issues and while there are a couple instances where content types have disappeared, they are all for earlier versions of Drupal and I assume do not apply to me. I am currently running Drupal 7.41 (just updated today).
Any creative suggestions on where to look next to try to resolve this issue are most appreciated. I'm truly stumped!
