I've recently switched servers and have developed a problem with WordPress. When I click on the tabs at the top of the page, the page downloads instead of opens. This occurs with only the pages in the 2nd tier of pages, other pages open ok if the direct link is cut and pasted into the address bar. Initially, every page was doing this due something in the wordpress setup forcing the site to run on PHP4, instead of PHP5 on the new server. This has been fixed but these last two pages are still causing issues.
However, I've opened this up at home with Firefox 3.6 and no problems. The server admin also had no problems (with Firefox I think). I'm using IE6 and Chrome at work which is where I'm having the problems. Cache and cookies reset but still same issue. Any ideas?
