PageView cache cannot be evaluated. ... ERROR

 PageView cache cannot be evaluated. Please recompile.

This error occurred this morning. Every page does not show except for SEARCH. Anyone an idea what happened? Did facebook or any thirdparty element delete another file?

solved, please delete this posting. By the way, why cant i delete it myself?

There is a time limit on deleting posts.  I would ask that the duplicate entry be removed or hidden.  By the way, the forum is more helpful to others when you post the solutions.  My guess is that you cleared the file caches and let them rebuild.  However, it would be nice to know.

It was my own fault. I must have changed the setting for the folder "cache". It was not writeable anymore. After changing it back, everything functioned again.
