After installing Akeeba I have two problems.
First problem
I see an error on the configuration page (attachment 1).
However, the configuration seems to save itself correctly.
The backup is performed.
Second problem.
In the front end the login no longer works. When the key is pressed, the login is not performed (attachment 3) and error 400 is visible in the console (attachment 2).
With Akkeba deactivated the login works correctly.
Thank you.
