@avl said in Google sites (some) not working in Opera 53.0.2907.68:
Have you tried disabling your installed extensions?
Yes.
I tried with a new profile with no extension but did not connect.
Now I discovered that sites that use recaptcha didn't work too.
Soon the new MacOS Mojave will be released then I will try a clean install of MacOS with a new install of Opera, to see if work.
Thanks for your help.
