SnappyMail Version 2.28.1 - Unable To Access Webmail After CyberPanel Upgrade

This community is (almost) dead. Nobody cares I guess. It’s been like 20 days…
Anyways, I fixed it myself.

[SOLUTION]

  • Login to your Cyberpanel instance
  • Go to PHP → Edit PHP Configs → Advanced
  • Select your default Cyberpanel PHP version (whichever it may be, in my case, 7.4)
  • Scroll down to the section disable_functions =
  • Find and delete the following 2 PHP Functions from the list:
    • pcnt_signal
    • pcntl_async_signals
  • Click Save Changes
  • Voila.

Note: If it still doesn’t work, reboot your Linux server, and it should definitely work.
