I just updated the new version of ALidropship and now my website is blank... I don't even know how to start to fix this
If it's the 500 server error after updating that others are reporting then try this first: https://forum.alidropship.com/threads/my-website-is-down-with-alidropship-hosting.8619/
Do you see any errors via cPanel? You should have a icon labelled "errors"
Also deactivate all of the Alidropship plugins to troubleshoot.
