I'm gettin this error:

There has been an error processing your request
Please check error log for more info. You can check error log in the control panel if it is functional. Otherwise, refer to error log located in your web server

I canno't access error logs so I canno't post the errors. And it looks like I'm not the first person gettin' this error and no fix.
