Hello
> LATEST Chrome Version 80.0.3987.162 (Official Build) (64-bit) > shows invalid hash error when entering room from moodle OM plugin : I am seeing that on Firefox 68.6.0esr on linux (SL 7.7). That's the latest up-to-date version on RHEL and its derivatives. Separately, I run into an SSL-related error message that was an array dump in the user's browser. It contained an SSLsomething element with value 20 and it was caused by having the SSL certificate in the keystore, but not the SSL key. I solved it, so I can no longer reproduce it. The problem with that array is that it includes the OM administrator password in the URL of the plugin's request to the OM backend. Cheers, Z
