I think this is the same problem I may have had or been having... Fought with a computer from like 5pm to 11pm yesterday...
Found out this afternoon that it's a PHP Tools bug that with version 1.82.20293 or newer if you have a space in the folder name, the page won't display and it won't start... remove the space in the folder name and it works... I downgraded the php version on the computer this afternoon and using version 1.81.19965 it all works like normal... Hopefully you guys can get this fixed soon...
And my main account, I can't seem to post or anything anymore on this support forum... It just sits saying awaiting approval. Would like to be able to use it again.
