Concrete5 5.7.1 marketplace: Can't install add-ons
An unexpected error occurred.
Class \Concrete\Attribute\Rating\Service does not exist
I tried with a fresh Concrete5 installation...same issue.
System: CentOS 6.5, PHP 5.5x MySQL 5.5x, Apache 2.2x
this has been reported as a bug.
If your site is linked to the marketplace you might be able to install by.
Logging into the markeplace outside of your site - go to concrete5.org and login.
Then buy the item you want (free or paid - all the same).
After doing this assign the licence to your 5.7.1 project.
Go back to your website and login and you hopefully can download and install.
I was able to on mine. Let us know if it works ok.
transition. Thanks for taking time to respond.
