I am trying to access my database table through phpmyadmin where the database has around 20 tables in it. When I try accessing three particular tables it is showing Gateway error on phpmyadmin. But the rest of the database table are working properly and also my software is working properly other than where it needs those particular tables. When I tried to repair table it exactly got stuck in the tables which seem to have problem. I do not know what to do other than reporting it to my hosting provider.
I an answering my own question :
I solved this issue by restarting the network with the following command
and changed the folder permission.
