I have the module that worked fine in Moodle 2.0,2.1,2.2 and 2.3
But since Moodle 2.3.1 users started send me emails that it doesn't work.
I installed Moodle 2.3.3 and tried to test my plugin but it doesn't work at all. It can be installed. When i login to the site as admin i am not requested to do update (this was the case in all previous versions).
Also i just checked some other plugins (not my, but other very popular plugins ) and i see the same problem. I copy a plugin to /mod/ folder and nothing . I am not requested to install new found plugins.
Were there major changes since 2.3.1 version? What are that changes?
