Issue with nextcloud after upgrading to 30.0.11

Hello,

After upgrading nextcloud to 30.0.11, I am greeted by a blank white page and an automatic download of an “index.php” file every time I visit its .onion address. I have tried using Firefox and Tor Browser from two different devices, with same result. Other services allsar m

I am travelling and thus am unable to check its .local address.

I disabled all non-native apps. Still no luck. Then tried to downgrade to v. 29 and received a notification that the downgrade failed.

Thanks in advance for the help!
