"Blank page" too often lately...

Somehow in few last days about every third or forth post is "blank page". While post is done and it is on forum, still - somewhat litlebit anoying...

Earler was may be every 30 or even rarer this blank page.

There have not been any modifications in these last days...

Is it somehow punBB problem?

(I am still using 1.2.14, - waiting for 1.3).

Re: "Blank page" too often lately...

A blank page? Well, that really doesn't tell us much. Check your error_log and see if there are any interesting errors there, or enable display_errors and paste the error you get when you get a white screen.

Re: "Blank page" too often lately...

iconv? That's not PunBB core, what did you edit in there?

I have modified russian PunBB, and long ago I atempted to make modification with YouTube BBCode.
But was unsuccesful.

But it was some half year ago...

Re: "Blank page" too often lately...

Well, the iconv function is never used in PunBB, so the problem is due to one of your modifications.

But only in last few days become this now even every 2 or 3 post as blank page...

:-((((((((((

Re: "Blank page" too often lately...

Probably it has to do with email subscriptions.
Paste your include/email.php so I can take a look at it and find a way to remove the iconv calls.

All or only this file?

I am waiting for 1.3 becouse of modifications...

I changed in options that now members can not subscribe to topics, I guess this could help.

Re: "Blank page" too often lately...
