Hi, @rogierlankhorst all I can tell you right now is that when I saw that error message I sent you, I took that screenshot, which I saw in other sites as well before. I then clicked refresh and it appeared to be normal. I have NOT updated to the next version of Really Simple SSL as many of my sites are running ClassicPress (the WP 4.9 fork) so I wanted to ask if that could have caused the error message or what may be going on. My sites are hosted w/Blue Host yet I have very strong wifi at home – just not great with SSL.
I can try updating the plugin on some demo sites in the meantime. I’ll read some more on it as well.
