Thanks again for your help. I was having trouble loading this forum yesterday for some reason. Not long after I posted I found the page that told me to load that URL for debug info. The funny thing is that it hangs when trying to load, too. I have tried the same URL for a few different pages on my wiki, and they all hang when trying to load indexer.php.
I read this page:
http://www.sitepoint.com/blogs/2005/11/03/web-bugs-for-job-scheduling-hack-or-solution/
Which has some pretty good info on the indexer script and what it does. It didn't really help me to solve my problem, though. I have NoScript installed in FireFox, and thought that might be the issue, but then quickly realized that the same thing happens in IE 8. I have looked at the actual script on my server, and it is in the right folder with the same permissions as everything else. I basically have an uncustomized install, I haven't done anything special at all aside from the install instructions.
I'm wondering why no one else has had this problem, because I am fairly certain that I haven't done anything out of the ordinary. I have also tried loading it from different computers in my network, and they all have the same issue.
I'm going to try to solve this still. If anyone has any help that would be great. If I figure out the issue I will let you all know.
