nima1981My blog http://www.economicsjunkie.com/ was throwing a white screen from time to time. (Usually 1 week after the installation it would begin acting up) Not even the admin section is accessible then. It is wordpress 2.8.5.
Then, when I restarted the apache server, it would always work again for a little while until it started crashing again. I was using WP Cache.
I deactivated the plugin and had no problems during that time.
Then I switched to WP Supercache and deleted the old cashing plugin. It went fine for 1 week and then started crashing again. After restarting apache it would always work for a little while until posting a white screen again.
I found absolutely nothing in the php/apache error logs.
I tried different versions of supercache, always with the same result ultimately.
I then disabled wp supercache and had no white screens since then.
Then I installed the latest plugin again, and activated the debugging. The following lines showed up before the next white screen started occurring again:

I looked for 'ob_start' in my plugins folder without success.
What can I do so wp supercache stops generating white screens?
