Having logged in this morning and got faced with a white screen instead of my profile page, I immediately suspected a memory issue. Was surprised though, since some months ago when I had the white-page issue frequently I fixed it by getting the server admin to upgrade the php memory to 128Mb (from 64Mb).

Tests showed it was only MY profile, no-one elses revealed the white screen, even if I logged in as a different superadmin. Test mode revealed nothing so I set about disabling the CB tabs one by one, and found it to be the Forum Plugin (disabling the tab didn't help, had to disable the whole plugin).

Now given that my Kunena forum has over 2350 posts, 286 of them being mine (I am by far the biggest quantity forum poster), I don't know if that is a lot of posts for the plugin to trawl through but it was set to display only last 10 links on the profile tab. Could it really be the Forum CB Plugin eating memory and causing the bail-out? If it is, then the post count will start to catch-up with other members and cause the problem to spread (the website is less than 7-months old).

I've disabled the plugin for now, so I have one less tab on members' profiles. But is there anything else I can do?

Have CB 1.4 installed.

Started happening again this morning, even though the CB Forum Plugin is disabled (yesterday I could switc the plugin on and off and reproduce the whitepage error off and on accordingly).

So now it is starting to bug me.

Below is my debug output. There is a syntax error showing up which I know nothing about. Same error shows on every page I visit with debug on, so I doubt it is causing the problem.

Error logs don't show anything related - only a problem with the rokweather module, which everyone who has the rokweather module is experiencing, due to google changing the API - guys at RT are looking into that.

I hope you can get some info from the debug for me.

Switched off Profile Book and it works now.

Switching ON CB Forum Integration Plugin, or CB Profile Gallery, or CB Profile Book, breaks my website.

Many thanks Krileon, you seem to have located the problem.

I disabled roknewspager and was able to get all the CB plugins back.
