XAMPP was working correctly earlier this morning, but after doing some Wordpress plugin updates and resyncing with Github and Pantheon, MySQL now will start, run for a few seconds, and then shut down. When looking at mysql_error.log, I see this:
InnoDB: using atomic writes.

I don't see any obvious errors.
Any thoughts on how I could either get more detailed error information or how to fix this? Thanks!
UPDATE
In the Windows Event Viewer, I was able to get the following error description:
Slave I/O: Fatal error: Invalid (empty) username when attempting to connect to the master server. Connection attempt terminated. Internal MariaDB error code: 1593

I used Xampp a few hours ago wanted to start mysqlserver again but it gave me a error message that mysql shut down unexpectedly
enter image description here
And yes the port is not used checked it with netstat -an | findstr "3306" command
and even tried to change the port to 3307 but neither that worked
And the error logs show no error:

If your MySql is new without important databases, you can try these steps:
Shut down your Xampp server
Go to C:\xampp\mysql\data directory
delete the ibdata1 file
Restart your Xampp server
Deleting ibdata1 file may destroy your tables, backup everything.
I'm using XAMPP version 3.2.4 and it was working normally for a while, but suddenly today when trying to start MYSQL it refuse to start and logs file display:

I tried to run MySQL on XAMPP v3.2.4 - and I get the following error. It did work before.

I don't understand why this happening. Can anyone help me to get rid of this error?
I have installed xampp server in my pc. First time creating database and insert data into database using phpmyadmin page was error free. For some table more than 1GB size i changed some configuration file settings like memory_limit, max_data_size. When I restarted the server and open the phpmyadmin page it is showing nothing (no error, no data). I don't understand the problem, already undo all configuration changes but still not working.
