I've succesfully setup wp-o-matic, using webcron.org.
Now I'm trying to setup W3 Total Cache with CDN (S3).
To keep a long story short: When WP-O-Matic is activated, the CDN function of W3TC doesn't work. Nothing happens when clicking the 'test button' or trying to upload files.
After de-activating WP-O-Matic, this works perfectly.
When opening the support page of the W3TC plugin, the WP-O-Matic settingspage shows up instead of the contact form.
I've also submitted this bug to the W3TC developer.
Anyone who knows what's going on?
