Hello to everyone.
So I have 2.2. AMPPS. I logged OFF the PC without turning off the MySQL in Apache Server. After starting AMPPS later the MySQL server won't start, so I did this:

Delete all the files from mysql like mysql-bin.*,  mysql-bin.index, ib*, etc without deleting any folder.
Then I restart the AMPPS and it all the server started. But now one of the database is not working. Any table that I click I get this error: #1146 - Table "xxx" doesn't exist.

It is not the first time I did this fail about forgetting to turning of the MySQL and Apache server and after that I always get this error. And I always lose all the data ://

But what is this bug? I really hope there is solution, how to get back my lost tables..
Because if I lost them now I really lost a lot of time.. :/

Ok after two hours I found the solution:

i found a way to fix this. just follow my steps and mysql will start again.

1. Go to Ampps\mysql\data

2. Create a "Backup" folder under data

3. Move those files to your Backup folder
Quote
innodb_index_stats.frm
innodb_index_stats.ibd
innodb_table_stats.frm
innodb_table_stats.ibd
slave_master_info.ibd
slave_relay_log_info.frm
slave_relay_log_info.ibd
slave_worker_info.frm
slave_worker_info.ibd
4. now open control panel and click on start under mysql

5. smile :)
