Has anyone ran in to this problem. After having Drupal websites hosted on the same share BlueHost server. About 3 to 4 months later all the sites showing "500 Internal Server Error" everytime I try to log in to admin account, create new account or log in to user account. Website itself runs just fine, just now I cannot log in to admin account and modify anything. Was told by my Hosting company that it is a common Drupal problem in the share hosting servers. I kinda doubt that since there are hundreds of thousands of Drupal installs on share servers. If everyone had this problem I there are definitely might have been some law suites for failing to warn users of problem with installing Drupal on shared servers. Any help would be greatly appreciated
Don't know anything really about Drupal or this particular problem, but whenever I see an Apache error like that, I run straight to the Apache error log. You'll usually find something more useful and from there you may be able to work out the problem.
Yeah, see if you see anything in the logs.. I had this problem once but it was like 2 years ago and i dont remember exactly how i fixed it.. I *think* it was either HTACCESS related or PHP.INI related..
