Hi, my site EstateRound.com (http://www.estateround.com) has been down without notice and uknown reason. when I entered my site I found this error
Content visible to registered users only.
and when I take a look at index.php I found this code (line 163-168)
Content visible to registered users only.

I wonder why my site down because I've looked at it when I were at office, after 4 hours go home and found my site down. I didn't do anything before it went down. No modifiaction, no upload, no FTP

I can still logged-in to admin panel but I can't manage any "links" or "category" menu when I entered I found this error
Content visible to registered users only.
here is my code (line 74-77)
Content visible to registered users only.

Please help :cry:

Ok, it fixed after I try to repair PLD_CATEGORY table via Phpmyadmin. But I don't know why this is happen :shock:

This happens occasionally on ALL databases...something gets corrupted. This can be the result of a power surge on the server, or some known linux kernal issues, etc.
As long as this does not happen too often, I would not be worried.
Of course, you should always have a backup of your database that is not too old.
