Non-cookie members are seeing blank page...
 

Ok, I'll start from the beginning...

I accidentally deleted one of my styles. (Yeah I know, don't ask).

My other style was exactly the same except from colors, so I imported it and set the colors correctly, then I went into the database and set the styleid to 1 (so it's the default template set etc).

But now for some reason, when SOME people are visiting (not all people though) it doesn't show them the main page, all they see it a blank white page.

What are the common reasons for blank pages? Missing templates?

Missing, or blank templates or bad PHP code I'd say would be the main reasons.

In the vB Options get it to add the template names to the HTML so that you can view source and see if its trying to display any templates.

Found it! I went through index.php searching for the word 'template' and whenever it was an actual template call I looked if I had that template installed. Turned out I found one (for unregistered users) that when I'd created it I'd only done so in the default style...

Phew. :)

Thanks for your help. Am I able to make this thread answered??

As the thread starter, you should be able to see a "Mark Answered" link at the top and bottom of this thread. Just click on it. :)

Yeah, I got that too. I will let Chen know.

I've just come back and it's now a tick - did I click it twice perhaps?

Aaaah... that may be it...
