Ok, is a bug with the new version, im 99.99% sure now... removed a website that was working before and has no traffic (for testing stuff) and created it back, now im getting 403 error on that website too... is there a way to downgrade aapanel? ...
ERR_HTTP2_PROTOCOL_ERROR
Ended up reinstalling the panel, added the websites back, got the bug again, i think its because the SSL... removed all the previous SSL certificates and now it works, but due to the reinstalling of the panel, i cant see my old databases... is there any command to show the databases in the panel?

please check/www/backup/panel/ dir
if there exist content overwrite the latest default.db to the data directory of the panel to restore
just lite
copy
/www/backup/panel/2020-01-19/data/default.db
overwrite
/www/server/panel//data/default.db
aaPanel_Jose ok, databases are back, but still cant create a new database... says the password is wrong, and all the databases, when i click on "tools" to check the tables, show 0 tables (altho the data and tables are there, they work, but i guess they are not connected correctly to the panel)
LCDraws
Please try to reset mysql root password
aaPanel_Jose ok, that fixed the issue 
2 months later
