Apache Friends Support Forum

Hi,

I'm a newbie using XAMPP. My setup was working fine a few days ago, but today when I opened the XAMPP Control Panel, Apache started as normal, but MySQL won't. Here's the error log report:

2014-01-27 18:27:19 1924 [Note] Plugin 'FEDERATED' is disabled.
2014-01-27 18:27:19 1158 InnoDB: Warning: Using innodb_additional_mem_pool_size is DEPRECATED. This option may be removed in future releases, together with the option innodb_use_sys_malloc and with the InnoDB's internal memory allocator.

2014-01-27 18:27:19 1924 [ERROR] InnoDB: Attempted to open a previously opened tablespace. Previous tablespace cs5017/users uses space ID: 1 at filepath: .\cs5017\users.ibd. Cannot open tablespace mysql/innodb_table_stats which uses space ID: 1 at filepath: .\mysql\innodb_table_stats.ibd
InnoDB: Error: could not open single-table tablespace file .\mysql\innodb_table_stats.ibd
InnoDB: We do not continue the crash recovery, because the table may become
InnoDB: corrupt if we cannot apply the log records in the InnoDB log to it.
InnoDB: To fix the problem and start mysqld:
InnoDB: 1) If there is a permission problem in the file and mysqld cannot
InnoDB: open the file, you should modify the permissions.
InnoDB: 2) If the table is not needed, or you can restore it from a backup,
InnoDB: then you can remove the .ibd file, and InnoDB will do a normal
InnoDB: crash recovery and ignore that table.
InnoDB: 3) If the file system or the disk is broken, and you cannot remove
InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf
InnoDB: and force InnoDB to continue crash recovery here.

Does anyone know what my problem is?

Thanks for help!
