I have a wordpress site which is acting strange lately. It seems like the database is spontaneously rolling back a few hours from time to time. I have noticed it happen at least four times.
- When I updated to wordpress 3.5, after a short time, maybe 30-60 minutes I noticed the nag to upgrade was back. I ran the upgrade a second time, even though I was certain that I had already upgraded.
- I added a new category and changed a widget on one of my sidebars, only to find that my changes were gone the next day and I had to redo them.
- I added a post yesterday, linked to it in various places and then returned several hours later to find the post missing. I rewrote the post from memory and put it back on the site.
- This morning when I went to the site, the original post was back and the one that I had recreated from memory was gone. The post's id number was the same as the previous day. I think there was also a draft post that disappeared and reappeared as well.
One last clue which may or may not be related is that when I go to a page on the blog that should generate a 404 message I get a single piece of text which says: "defaced by t3ll0" I noticed this recently, within the last few weeks. I'm not sure how long it has been like that.
I ran Sucuri Scanner, and it found no evidence of malware. Any suggestions of how to troubleshoot this? Could this be a problem with my database rather than wordpress?
UPDATE: It appears that the primary problem I was noticing was because of two versions of the site being up simultaneously. The DNS settings had not been updated to the new site. I'm still investigating if the site was hacked.
