I'm using w3 total cache (0.9.2.9) and I updated it yesterday, everything works fine but I've detected that it's regenerating empty page enhanced files. The browser is showing white pages.
When I flush cache files, the cache files are generated perfectly but when W3TC automatically regenerates them somethimes the files are there but they are empty.
The unique error was:
PHP Fatal error: Call to undefined function w3_http_get() in /home/***/www/wp-content/plugins/w3-total-cache/lib/W3/Dispatcher.php on line 238
I fixed adding in Line 6:
w3_require_once(W3TC_INC_DIR . '/functions/http.php');
to
/home/***/www/wp-content/plugins/w3-total-cache/lib/W3/PgCacheFlush.php
But the problem persits and I don't have errors comming and debug alerts.
