IE7/PHP-debugging?

Hello I'm having troble viweing a page. I get the fault "Webbsidan kan inte visas" which can be translated with "The webpage can not be viewed". When I reload the page the system I've created it renders perfectly. This would be likely to depend on a logical fault in the code, BUT the thing is that the system only behaves like this in Internet Explorer. I've tested the system in Opera and Firefox and there it is no problems. I've also tested to setting diffrent time-outs but that doesn't seem to be the issue. My question: IS there anyone who knows about some utility to check what's going wrong in IE together with PHP-applications? Would be happy to have that utility because IE itself doesn't explan anything about errors... Best regards /Gustav Wiberg No virus found in this outgoing message. Checked by AVG Free Edition.
