Can't enter Username in checkout/registration

VM 2.0.0, JM1.7.3

I have been searching for this in the forum for a while. I have found a few similar problems, but the fixes were not explained enough for me.

When unregistered user tries to register during checkout, the field "Username" is locked from entering text.

I have read on the forum that one way to fix this is going into the database and setting read-only form 1 to 0. I have not been able to find this value in any of the files. If someone could please help me with this I would be very grateful.

Go to PHP Admin, select the database.
Find Prefix_virtuemart_userfields the select COM_VIRTUEMART_USERNAME and check if readonly is set to 0.
Its probably on readonly so you cant give any input.
