Roundcube login problem

Intel(R) Xeon(R) CPU E5-2630 v4 @ 2.20GHz, 4 cores
OS type and version Ubuntu Linux 20.04.4
Virtualmin version 7.0-4

Hey guys,

I’m just starting with Virtualmin and I installed a webmail. It was working fine until the last time I checked (a couple of messes ago). Today I went to try to login for a client and I get this message after entering the password: (message appears as a yellow alert in the corner of the RoundCube login screen)


“Invalid Request! No data was saved.”


Does anyone know how to solve?
