I've got the delightful job of managing a SP2010 instance as one of my systems. There are two main 'sites' and for some reason the asset selection section will not display any content (screenshot: imgur link). This is happening across both sites and as far as I know the views haven't been touched, and all file modifications for the templates are pre-2012. This was working flawlessly a fortnight ago.
I've done the following:
- Restarted the IIS server and then the whole server (it's dedicated for SP)
- Cleared the XML cache in Config and reset the timer
- Completely disabled the Publishing* features and re-enabled them
... to no avail.
The error will be displayed for any item on the left. I'm by no means a SharePoint expert but I did try and decipher the logs; all of which display these same lines when the error occurs:

If anyone's stumbled into something like this before and can help, or knows a specific resource to check, I'd be quite thankful.
