Hi ddur.

Thank you for your tips. I disabled all the plugins and enabled them one by one and discovered that the problem occurred when I enabled a plugin called “WP Email Users”. After uninstalled that plugin the Warp apparently started working correctly.
Thank you very much for your help.

Hi.
Yes, I am logged in as administrator and all the other plugins save correctly.
The sessions is not expired and I tried several times and with different browsers. I also tried to uninstall and reinstall but it remains the same. If you want I can send you the admin login by PM or email.

Thank you.
Mauro.
