I just upgraded from 0.9.9 to 1.2.
When I visit a page, everything is cached like it is supposed to; however, I have a custom script that I use to control what pages get cached and when. In this script I make the following call:
do_action( 'gc_cache', 'rebuild', 'homepage' );
I get this: <!-- Page not cached by WP Super Cache. Blank Page. Check output buffer usage by plugins. -->
I have tried several variations on the URL but nothing is working. This worked fine in version 0.9.9, what changed?
In the debug log, I get a bunch of messages saying that the buffer is blank - looks like the do_action call is not loading the page.
