Hi,
I have been using W3 for a while and was able to get page load times in the sub-one second range. I am using a theme which adds an adaptive layer for mobile devices. I have added the mobile user agents to the page cache, cdn, and minify Rejected user agents field. I disabled all others, object cache, database cache, etc.
I enabled useragent groups pass through mode and tried everything else that I can think of. When I have ANY of the W3 features enabled and visit the site from a mobile browser I get a blank white page. Nothing else. View source shows nothing at all. What do I need to do to be able to enable w3 again. My page load time is suffering without it.
