Error: Cache not supported (1 reply)

That last upgrade went south big time: I can log in but....nothing shows up except a message that says "Cache not supported" and a couple of links which when clicked just take me back to the login page. (image attache) I have:

• Clear browser cache, tried different browsers
• Deleted all the content in the TMP folder
• Manually remove any extra plugins I added myself

Here is Pastebin copy of an entry in the error log: http://shorty.3rdlof.com/p4d5m

I have search for that specific sentences "Cache not supported" and so far I cannot seem to find a single example of something similar.

Any hints will me most welcome.

Thanks
