Blank Pages

[yaashul]

I'm getting blank pages on my Forum. I have enabled php debug mode on and found no error whatsoever. These blank pages comes so rarely that we dont know the exact ways to reproduce this error. When this blank page come php dont show anything in logs as well. I tried using different Browser (IE8 & firefox); the problem is coming in both browser. I tried using other system & isp problem persist on those system as well. Can you please suggest where to start looking for problem & its probable solution. I do have many screenshot of the problem incase u need them I'll give you those.

This is going to take some heavy duty trouble shooting. Your going to need to use a program like Winmerge to compare all your files to a good copy to find out where the mistake is. The difficulty of this method will varry depending on the mod's you have installed.

Another thing to keep in mind is that you need to use a proper file editing program such as Notepad++ that will save the files in the same encoding they came in, in this case, UTF-8 w/o BOM. Notepad++ will even work with a lot of the popular FTP programs (like CrossFTP) so when you hit Edit in the FTP program, it opens notepad, then saving in Notepad++ automatically uploads the file.

If you have already edited any of your language files using the regular windows notepad.exe or any other program that cannot save in UTF-8 Without BOM, what you need to do is download, install and run notepad++ (or edit from ftp into notepad++), either way, when editing the file, in the menu up top, hit format, then chose "Convert to UTF-8 Without BOM" and then save and re-upload if needed.

God luck, you'll need it.

I use Cute FTP for ftp & file editing so I dont think I need to check this "UTF-8 Without BOM". But i do open all the mods in Notepad only... I directly edit the files using Cute FTP & save them...

I'm using few mods created by this forum...

Should I reimplement all the mod in phpbb vanila to solve this issue coz this error is so rare. I get it on 4 times out of 4000 pages I open...

I findout why I'm getting those blank pages... it is due to Antispam mod by Exreaction but not i'm trying to remove this Mod I'm getting this error...

Please download the latest UMIL

What should i do to remove this mod completely from my Forum & its database....

[yaashul]

I'm successful in uninstalling this Mod but still I'm getting those blank pages... So this has to be a problem with mod provided by this website...

where should I look first?

Start with activating phpBB debug to see if any error shows up.

Pretty easy, just install GYM fully, and then uninstall the forum modules for RSS and HTML output types, using the install link in corresponding acp pages.

We had a very similar problem; but it happened consistently. That is, the forum completely disappeared from view. There were 21 bytes of blank in each page. Enabling DEBUG and DEBUG_EXTRA gave no further information. It started happening suddenly. There was no system upgrade or any mod installation.

We solved it by wiping out the phpbb/cache directory except the index.htm and .htaccess files. It turns out phpbb did some SQL query caching that went wrong and messed up the session entries. I'm not clear what this caching does, but it seems like a dangerous component that can go wrong silently.

We are running phpBB 3.0.5 on a FreeBSD system with mysql and apache2.
