Website visitors are able to login in using email address but when you click "create an account" for new visitors I get sent to a page with this error. How can I fix this?
Liquid error: Could not find asset snippets/ci-plus.register.liquid
Seems this file 'ci-plus.register.liquid' belongs to some app and you uninstall the app.
While uninstalling to app, app removed their file from snippets but didn't remove the code from the file.
Now to fix it you have to manually edit the file 'customers/register.liquid' under Templates and remove the unnecessary code.
Alternatively contact the app author and ask them to remove the code.
