Error in AbstractFactory.php on user registration

[matthias_hausen]

Hi users,

I have following problem and I hope somebody can help me find the solution.

If an user creates an account, they get an Error 500, the detailed error is this:

Fatal error: 

    Uncaught Error: 
    Call to a member function get() on null in /html/[magento-installation]/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php:126

    Stack trace:

        Magento\CatalogInven in /html/[magento-installation]/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 126

This happens since I installed the extension Restrict Fake Registration by Magecomp. Now I'm not quite sure what I could try to fix this issue.

I'm using Magento 2.1.7 and PHP 7.0

Anybody has an idea and could help me please? ^^
Thank you and best regards

Try to uninstall this and check if all works then have to check plugin codebase it may be issue with used object manager class in this plugin. 

Or you can contact to this extension provider, might be this pluign not support your version or php version.
