I have been using 11.3 (and previous versions) for awhile now, I haven't had any issues installing updates, plugins, etc. I just downloaded 12.0 beta 4 and I can't install any plugins. I get multiple error messages (see screenshot).
As I said I've had no issues with previous versions, I started with an empty cache, my proxy settings are set to 'Use System proxy settings'. I'm not sure how to check if my firewall is blocking traffic (it wasn't with 11.3) Any ideas? Thanks
