Answer 1

I had the same problem. I tried all the solution others has proposed, and unfortunately nothing worked.

After spending hours on searching for the solution in Google I finally found this

1. Open my.ini (my.cnf on linux-based systems and Mac)
2. Look for [mysqld]
3. Just below [mysqld] insert innodb_force_recovery = 1
4. Start MySQL Service
5. Stop MySQL Service
6. Remove the line from my.ini (innodb_force_recovery = 1)
7. Start MySQL Service

Worked perfect in my case.

I hope this will solve your problem.
