From the Saltcorn.com page I log in as administrator, but it doesn't allow me to make any changes to both my own user and the project itself. I tried installing it directly to the system and trying to access from the localhost does't allow me to even log in as administrator.
just to be clear, you created a project at https://saltcorn.com/tenant/create, then you create a user and then you log in to your project and you can create tables
if you installed in docker, I also had a problem with creating an administrator, while installing on ubuntu is quite simple and following the instructions on the page everything should work as it should. https://wiki.saltcorn.com/view/ShowPage/install-on-ubuntu
please send a screenshot if you get any errors
Something like that, I created a project in https:/saltcorn.com/tenant/create, after creating the administrator I was working normal for a few weeks, until just a few days ago I logged in with that administrator account and did not give me the permissions to modify anything. I had a backup from previous days and tried to do it locally from Windows, but that way I wouldn’t even log in, so from the terminal create another administrator user and only then let me make the modifications.
