QuestionAfter installing v2.1.5 of the module on M2.2.6, we cannot save product  http://prntscr.com/llwor2

Solution: 
Could you please check if  Catalog Price Scope config is Store view? (Configuration -> Catalog -> Catalog -> Price ->Catalog Price Scope )
http://prntscr.com/llyx3p

FYI, it's the configuration to enable our extension on Backend. Thus, if you keep Catalog Price Scope config as Website or Global, it means that our extension is enabled in code but not on Backend, the issue will appear.
