Magento 2 | Component manager wont work after migration

Question

I finally managed to migrate my Magento1 (1.9.1.0) to Magento 2 (2.1.3) with the Data-migration tool from Magento.

Everything went well, after a few mapping issues and fixes for that the migration went straight trough.

But as soon i want to install a few extensions from the marketplace and i have to enter the keys (public & private) to login into the account i get a never ending "Please wait" -popup. After closing and reloading the Web setup wizard the keys are saved but the extension grid wont show... just another neverending "Please wait..." popup.

Do you guys know anything about that ?

Do you guys know how to fix that ?

What i've already tried:

• Reindexing
• Cleaned cache
• Reloading the site and tried again

Update:

Found a warning when entering the component-manager page:

The specified value "{{currentPage}}" is not a valid number. The value must match to the following regular expression: -?(\d+|\d+\.\d+|\.\d+)([eE][-+]?\d+)?

Still cant figure out why i cant get this to work.

Answer 1

Problem solved

Was an vcs-module wich wasnt configured correctly and by that it was conflicting with some Magento stuff.

After removing the module everything worked just fine again.
