@dunlix understood. I think that this error is caused by OSCP stapling - see https://support.mozilla.org/en-US/questions/1149911
Proxy error local emailer
I just activated the local emailer and getting a proxy error in /admin. Is this a bug? Hosting thru apache btw.
What do you see when you access your site without the proxy?
@julian I just disabled the local emailer and currently using mandrill but it doesnt send emails. The forum's not working as it should on some plugins..... gonna try reinstall
