I ran a nested query in the phpmyadmin, and it was taking a long time, so I killed the query from the terminal, and after that, browsing the table in phpmyadmin gives this error

`You have an error in your sql systac; check the manual that corresponds to your MYSQL server version for the right systax to use near ') LIMIT 0,25 at line 1

Phpmyadmin was appending a broken cached query.
I have tried everything, but nothing has changed. So I found a solution that is a phpmyadmin problem for logged-in users. I have logged out of the phpmyadmin and logged in with a different account, and again I have logged out of the account and logged in with the main account, and the problem is gone.
