When installing ITFlow with the itflow_install.sh script on Debian 12.9 the default value for "Max Execution Time" is 30. Seemingly it should be 300 according to the debug page (not to mention the demo enviroment) so I found this strange. This happened to me when testing ITFlow on my homelab environment as well as when I spooled up a production enviroment on Digital Ocean so I don't beleive it was a one off oddity.
This can be manually resolved by editing the php.ini file but I'm assuming this might be an oversight?
