Joomla 2.5.7 with VirtueMart 2 issue

[novjuzer]

Hey guys, after migrating my site from a sub-domain to the main domain i keep getting this error in the browser:
Warning: file_put_contents(E:\---\wwwroot\plugins\system\yt\includes\libs\minify\config.php) [function.file-put-contents]: failed to open stream: Permission denied in E:\---\wwwroot\libraries\joomla\filesystem\file.php on line 418

and this one in the back-end of virtuemart
Warning: file_put_contents(E:\---\wwwroot\cache\com_virtuemart.updates.ini) [function.file-put-contents]: failed to open stream: Permission denied in E:\---\wwwroot\libraries\joomla\filesystem\file.php on line 418

any idea what causes this?

Something to do with Joomla and config files looking for localhost (assuming your server is not a Windoze machine), not a VirtueMart issue. Did you migrate using Akeeba?
