Hi, I have the same problem after logging into my superadmin account. I can log into other employees' accounts without problems and everything works. However, when I log into the superadmin account, i.e. the main account, it shows me this problem.
PS version -> 1.7.7.4
PHP version -> I had 7.4 and everything worked, but when I got this error, I tried to reinstall to 7.2, but the change didn't help.
Did you manage to fix it or did you figure out where the error is, please?
Can you help me somebody please?
