I am working a SharePoint site with a custom masterpage and css. Everything displays just fine and the site functions with several subsites, and so forth. I have double-checked to ensure that important content placeholders were on the new masterpage, even if they were "hidden" from view.
However, a new issue came up this week: I was moved from a contributor to a designer list so that I could convert word files in a doc library in web pages. When that change happened, I lost the ability to select "add new items" to lists or add events to calendars. [not sure if causation, or just correlation] On a similar note, no one--not even those with higher permissions levels than me---can access the "site permissions" page in browser now (not sure if this coincides with my issue over the lists/calendars, but in both cases the notification "an unexpected error has occurred" comes up).
I temporarily switched a subsite to the default masterpage, and lists and site permissions page functioned fine--no error. Therefore, it appears as though something in the custom masterpage (or embedded css?) is causing this error to come up. But what could it be?
I ran across a forum question that mentioned a bug related to alternative css:http://social.technet.microsoft.com/Forums/sharepoint/en-US/53151269-dd61-4c71-8263-c1880450a1bb/sharepoint-2010-unable-to-access-site-settings-site-permissions-from-a-site-created-from-a-template Solutions said to check the correlation ID and use powershell. The guy in my department who checked the correlation ID said that nothing useful came up, and I got the impression that the powershell solution didn't work out for him either (I don't work on that side of things; I am on the design side).
So, does anyone have any idea what the problem could be? Again, I have checked and double-checked those content placeholders in my custom masterpage - they are all there. I built the site using one of Randy Drisgill's masterpage templates. Up until this point, I haven't had any issues with the template, my custom code, etc.
