I'm using the latest update and getting the blank pages issue. In my case I didn't notice any difference whether adding a trailing slash or not, random pages (often the home page) would just be completely blank. Not even <html> and standard tags with no content, just nothing in the source.
I'd be happy to help with testing and submit bug reports, I am on a shared folder but can try and get access to log files if this helps. I have the plugin enabled with all settings except for Page Cache (Disk/Enhanced didn't make a difference to the issue) and that all works fine now. HTML isn't being minified but that's another issue altogether.
