Oh that is quite badā¦
Have you tried with Firefox V52.9.0esr?
It does still work for meā¦
Or maybe it is also a OS thing (if not only with most recent browser versions).
What OS (Windows, Linux, etc.) do you run?
Is it the same same for all of them?
(Temporary) Workarounds
I canāt imagine it being on Memriseās end. Iāve no problems here (Chromium on Linux, but checked with Firefox too). According to my browser, Memriseās SSL certificateās just fine. I do sometimes get Chromiumās equivalent error message, but for other, perhaps-questionable-looking sites. Canāt imagine why youād get it for Memrise.
Is your version of Firefox out of date? Sometimes, weird things happen when itās too many versions behind.
If itās not too much trouble, please post here when you work out what the problem is. Iād be interested to know if itās just a settingās problem in your browser or if thereās some more disquieting reason.
I switched today DNS and the problem resolved itself.
Thanks for the comments guys.
