Thank you very much Ray. I changed to true. I had already gone through the Photos folder and I'm sure there was some garbage in there from them. All my member photos have the same naming convention because I rename them when new members submit. They submit images with the dumbest names and the most outrageous sizes. I usually end up downloading, fixing, renaming and re-uploading. But I will go back and double check to make sure the hacker didn't catch on to my naming convention and upload something that I wouldn't notice.
So, do you suppose this was just some hacking software that happened upon our site? Does this software just roam around the web searching out vulnerabilities? Do you think I should have further concerns? It's been a month and I haven't had trouble with any other sites.
Thank you again. I really appreciate your help.
