It means your shopify app didn’t install as expected

Shopify make too much problem for my erpnext , even i lose support after installed this app .

remove it with bench --site [sitename] uninstall-app erpnext_shopify

Thanks for your help , i removed then login with administrator and again installed from UI it;s work well .

But still my problem for sending email not solved , when i send email form erpnext nothing happened ,
How can i find what’s problem ?
