I tried shutting down XAMPP and deleting the ibdata1 already. Yesterday the server did still work, but when starting up today it didn't start anymore. I'm using the server for a PHP project using PHPMyAdmin.
This is the error log from XAMPP:

Can someone help me with this error i see the fatal error cannot allocate memory for buffer pool but not sure what this means or how to fix?
Also what may have caused this?
Thanks
After googling a bit i have added
innodb_buffer_pool_size = 20M
to my.cnf is this a solid fix?

XAMPP MySQL shuts down unexpectedly. I was trying to enable the configuration storage settings earlier, turned my PC off, and returned to this. I have uninstalled and reinstalled XAMPP within the past couple of days, changed port numbers to apache and setup a password.
I've deleted the ibdata1, ib_logfile0, and the ib_logfile1 files, and changes the port numbers to the my.ini and php.ini files.
Help would be appreciated.

I am running 2 locally hosted wp sites for testing on my Win 7 pc. Unfortunately windows update did a update install and reboot last night while wamp was online.
Usually I can fix this myself, but I am having no luck. After about 6 hours of search for a resolution I turn to you wonderful people.
PROBLEM: Orange Icon.
