I have been running EmonCMS 10.2.2 for several years in a shared hosting environment. It has worked perfectly.
Today (5 Feb 2023) I cannot login at all. I receive no error, the system just returns to the login screen. I have tried from Firefox, where I have had a page permanently open on the Feeds screen, and likewise from Chrome on Android, where again I have had a permanently open screen.
I have been sending JSON light data via GET for several years but this broke a few days ago and has possibly been sending garbage while I resolve the problem.
I have looked at the database and from the outside it looks OK, the API key and username is correct (obviously I cannot confirm the password is OK).
How can I get logged in again? Any guidance will be very welcome. I am quite familiar with php and MySQL so am happy to dig a little if required.
Thanks in advance
