Help, i change the URLs in configuration Virtualmart.

[pentagona1]

Hello to everyone. Thanks in advance for the help.
I did a very stupid think. I change the URLs of assets and media and etc. in the configuration of Virtualmart v. 3.0.8 and now my configuration and admin urls of virtualmart don't work. I paste doble the full path of my folder.

This is the error:
An error has occurred.
0 DirectoryIterator::__construct(/home/www/mysite/www///home/www/mysite/components/com_virtuemart/assets/images/availability/): failed to open dir: No such file or directory

Please, tell me how te edit and back the normal URLs path of config.

Thank You
Viktor

From where, manually change the paths from source code of the files of joomla.

I think when you update, then you can access the config again. I think I fixed that.
