Fatal error: Call to undefined function of_get_key_by_product()
If you got the above error then you need to use the following solutions
Go to plesk installation directory and then “admin\repository”
Delete the file “registry.xml file.”
Now,Restart plesk services
most properly the directory will be here C:\Program Files (x86)\Parallels\Plesk\admin\repository
confirm will fix the issue, i have test it and works ( for plesk 9)
i never try it for other version of plesk,,, u may try it, may it will work too
thanks
