Hello Rui,
Welcome to the Bacularis user group.
This error is because the memory for PHP has been exhausted. The solution is increasing the memory limit for PHP.
To solve it, please follow on the instruction described in this documentation chapter:
https://bacularis.app/doc/brief/troubleshooting.html#the-job-history-list-or-the-job-files-table-is-emptyIn short it is about increasing value in memory_limit option in the php.ini file. You can find it in /etc directory. You use Ubuntu, so there can be even two or three php.ini files. You need to change it in this file used by your web server. If you installed Bacularis with binary packages, please look on this in '/etc/php/*/fpm/' directory. After that there is needed restart PHP, for example for PHP 8.3 it is:
systemctl restart php8.3-fpm
Good luck :-)
Best regards,
Marcin Haba (gani)
