Happy issues with the manual upgrade of Taoba 7.7.

admin

Used the links given by forum masters to manually unlock the lugin.json file after 7.7, once locked, this prevents automatic repair to free version

To fix this problem, you need to chattr +i /www/server/panel/data/plugin.json, or offline, the store will not open, if not locked, it will restore the original data and cannot use premium plugins.
