Hi
I think I have the same error as in this ticket, but the resolution does not work for me.
https://www.akeeba.com/support/akeeba-backup/39476-cron-daemon-failed-opening-php.html
The error I get after twice installing it:
In AkeebaBackup.php line 232:
Failed opening required '/home/fotooase/public_html/administrator/components/com_akeeba/BackupEngine/Factory.php' (include_path='.:/opt/alt/php81/usr/share/pear:/opt/alt/php81/usr
/share/php:/usr/share/pear:/usr/share/php')
