Hi,
Hopefully someone can help with this issue. I've searched but can't find anything 
. After installing a theme I bought I run:
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento setup:static-content:deploy
Site looks good but when I try to login to admin I get the follow error:
1 exception(s):
Exception #0 (InvalidArgumentException): Invalid scope type ''
Exception #0 (InvalidArgumentException): Invalid scope type ''
