Hi Rodolfo,
Thanks for reply!
Finally, I got it handled. Not sure why, but the script pulled the PHP version 8 instead of 7.4.
As the error log was showing the ZIPArchive is missing, I've checked thatat the server and found that it is only missing in PHP 8 config.
Updated that and page was available again.
In WHM and cPanel the PHP was set to 7.4, but in dashboard it was 8.
Wired, but I changed in cPanel to 8 and then back to 7.4 and now all is running as it should.
Thx & cheers
