No idea.
I got all my .htaccess code from google cause I know nothing about it and I just wanted to run php functionality with htm files so I didn't have to do a full file extension overhaul just to run traffic reporting programs.
I have no deleted the .htaccess file (not before backing it up on my computer) and my site now loads again, yay! Also, hotlinking for my auctions is working again.
However, I STILL can't work out why my pages are trying to download instead of just loading in the browser, this is really weird.
At least I'm 1 step further than I was before..
If you want to view my page to check, it's:
http://pipelineae.com/
That one will load correctly, however this one will attempt to download:
http://pipelineae.com/index.htm
Actually, no it won't. I just followed those links and it worked..
But when I added www. to the latter, it attempted to download the index file..
Maybe it was the .htaccess file causing all the dramas and now it's just slowly clearing the server cache.
