WP Super Cache
Getting a blank white page for one post (5 posts)

    For one post I keep getting a blank white page in Chrome. It shows in FF, IE7 and Chrome Incognito.

    Any idea what could be the cause? This is the page: http://goo.gl/VwHFK

    As soon as I deactivate WP Super Cache is loads OK. Other pages / posts load fine too with WP Super Cache.

    I had the same problem with W3 Total Cache, and changing to Super seemed to fix it, until now.

    One feature (other than it not happening!) would be able to exclude individual posts from being cached while problems like this can be investigated.

    Update: I just realised that it only happens when I am logged in. So different to the problem with w3 total cache (which other people experienced).

    I logged out of WP in Chrome and the page loaded. I logged back in, the page did not load.

    Update: after reading a thread about problems with ob_start in other plugins (a thread which I did not understand much of!) I started deactivating plugins with ob_start in them.

    On deactivating WP Minify the page started loading again.
    Reactivated WP Minify, page blank again.

    So that seems to be the cause. May see if there are alternative minify plugins, although as it seems to only affect logged in users I may just leave it.

    UPDATE 2: Disabling just html minification fixed it.

    First thing I do is check the PHP error log for errors as a blank page is usually a PHP code problem. Was there anything there?

    I will have a look. If I can. I know I have a raw log and an error log, not sure about php error log though.
