Hello,

Yes, there are going to be lots of deprecations on SubjectsPlus4. SubjectsPlus 4.6 is meant for PHP 7.4. 
Our team is currently developing SubjectsPlus 5 which is built on PHP 8 with Symfony Framework and React.
You can follow the development on our wiki.
https://github.com/subjectsplus/SubjectsPlus/wiki/SP5-Development-Updates

Thanks,

SubjectsPlus Dev Team

[Mahendra Kumar Sahu]

Please provide the solution

[AFA]

can you share the version of the following:

php
mysql/mariadb

[charlesbr...@gmail.com]

The SubjectsPlus 5 Release Candidate is currently being tested at the University of Miami.
The first public release will require 4.6 to be updated to version 5, rather than a fresh install.
We'll keep the group up to date.

I used XAMP version V3,3,0
