I am testing my Joomla site on two different machines. One is a server side,
and the other is a virtual machine. I have a MySQL database for my site.
It works (root site page - login) on a virtual machine, but doesn't work on a server side computer.
Note that I don't have installed antivirus on a virtual machine,
and on a server side computer I have it. Also note that maybe, on MySQL,
the limit for password on a server side computer is of lenght 7, but for some reason,
longer password works on a virtual machine.

Could someone explain how to resolve this issue?
