Hi, I've been meddling!!
Was running PHP Triad on WIN NT - site worked fine. I needed to start using sessions though.
Changed to apache 1.3x, MySQL, PPH 4.06 on Win NT. Configured it all etc and it seems to works OK. The sessions work fine. When I went back to my site I found most of the pages where MySQL calls were made, were blank.
I diagnosed the problem to passing form variables. When I use a URL the field value is parsed OK.
When I use the same data in a form and click submit / return, I see the data in the Address bar of the browser, but the page is not parsed.
Any help would be great.
