My LS suddenly started producing problems, with the main survey admin home screen and the surveys list working okay, but when I tried to open a survey the page would only partially load and the links would be dead. (Screen shot below.)
I thought that the script files might have somehow gotten corrupted, so I did a database integrity check that did not indicate any problems.
I then tried doing a ComfortUpdate, and the only alert it gave me was about my modified favicon.ico file. However, when I finalized the ComfortUpdate, the Limesurvey screen came up completely blank.
I then tried to download the current version of LS and manually install it (preserving only config.php and /upload), but it still comes up completely blank.
What could be going on? I checked the permissions, which are set to 755. Is there something else that could be happening?
This is a terrible time for this to happen, since I was just about to launch an important survey tomorrow! If anyone can help me troubleshoot ASAP, I will greatly appreciate it!
