I started getting this error "An error occurred. Please wait a few moments and try again. If the problem persists, contact a system administrator."on some pages of our Dynamics CRM 2013, I noticed also that Developer Resources are failing (Screen Shot Below). Please any help could be highly appreciated.
Thanks.

I have the same question (0)If it's a On-premise crm take a look at event viewer that may provide more information about the error message or enable the trace and check the trace log to find the cause of the issue.
Also check whether anonymous authentication enabled in IIS for CRM web site.
