W3 total cache causing white screen of death

Hi,

A few days ago I found out that my website got a white screen of death, the problem only exists on a few pages. Only those pages are affected, all other pages work just fine.

After a few hours I was able to narrow the problem down to the page cache funtion of W3 total chache plugin. When I turn off the page caching the effected pages will work again. So at this moment my website is running without page caching, a not ideal situation.

I got this error in my error log around the time the problems started but i’m uncertain this is related.

PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0

I already invested hours in this problem and am not able to fix this. I would like to be able to use W3 again because this plugin worked well until this point in time.

I would appreciate your help,
Thanks
