I found a temporary solution to my looped login problem.
in the skin.conf file in the directory: /usr/local/directadmin/data/skins/evolution
in version 1.63.8 I had an entry:
version = master-1469
in version 1.63.9 the entry is:
version = develop-1885
when i replace skin.conf entry and i'll remove session file from /usr/local/directadmin/data/sessions and restart the directadmin by
service systemctl restart directadmin
then I can log in to the admin account.
Performing some operations on the page (for example: show all users) I get a message in the lower right corner with an orange background:
You cannot execute that command
The request you've made cannot be executed because it does not exist in your authority level
I see an entry in the security.log file:
*** User admin tried to execute / CMD_JSON_OPTIONS ***
I am waiting for some advice from the masters.
