Had some wonderfull Internet Explorer frustrations today and thought i’d share it with you.

When I copied a Drupal site from our testserver to my local machine i found out i couldn’t login to Drupal using Internet Explorer (7).
Firefox worked fine but IE refused 100% of the time. No error messages or warnings, the login block was emptied and you’d return to thesame page.
I did some research and turns out Internet Explorer makes a problem out of underscores in your domainname (whereas Firefox ignores it). Guess what i was using …
I changed my apache vhosts file and windows hosts file by removing the underscore for that particular site, rebooted apache and afterwards my login worked like a charm in IE.

Hope this helps someone .(be aware that I found more problems than this in using IE, sometimes just clearing your cookies would do the tric according to some users. Not in my case though).

PS: This has to be the 5.789.438th time i wished someone would just nuke IE of the planet…
