And XAMPP Control panel says:

Problem detected!
Port 80 in use by "Unable to open process" with PID 4!
Apache WILL NOT start without the configured ports free!
You need to uninstall/disable/reconfigure the blocking application
or reconfigure Apache and the Control Panel to listen on a different port

How can I fix this error?

Error: 1932 Table 'wikitest.wtl10n_cache' doesn't exist in engine (localhost)

Obviously that table is missing. Unfortunately we do not support 3d party products like mediawiki, you should ask in a support forum of mediawiki instead. This is clearly not a Xampp issue.

Port 80 in use by "Unable to open process" with PID 4!
