I have a website that was running very fine and i have not made a single change to the server or to the website until one day suddenly I have 2 problems.

1- i have a few IPB forums on the sever in Arabic and their encoding is always defaulting to Unicode. even when i return it to Arabic it still goes back to Unicode after chaging or refreshing the page.

2- I cant see any pages of one of my websites on IE but i can see them on FireFox (also bad encoding). but i can see the error pages. the pages are all in php (just a header and footer require tag)

so how can i fix this? the Resellerworkz techs have not been able to fix anything yet. although i believe it should be a simple thing with apache..

any thoughts please? this has been going for about a week now and it really hurt my website :/
