I apologise for the incorrect information.
My hosting provider, which runs servers on FreeBSD, somehow applied this PHP patch incorrectly yesterday, and as a result, data saving in Thirtybees within the back office wasn’t working across all PHP versions.
They’ve now fixed the issue and everything is working fine today. 🙂
Our good old TB 1.4.0 is now running on PHP 8.4, thanks to the patches from PS The Web Solution! It runs like a rocket, and after all our testing, there are no errors, warnings, or deprecation notices in the logs! Thanks guys, outstanding work!
