Here is our store.
We have installed the app Store Pickup + Delivery by Zapiet. However, After uninstalled the APP, we can't go to the check out page in our store. No response after clicking the check out button.
We have followed the Zapiet uninstall guideline to uninstalled.
Every time we need to refresh the page to go to the check out page.
Anyone can help us?
You need to contact the app developer directly.
If you have a backup of your theme then just publish a copy of that and test it.
(dont modify your cleans backups make a duplicate)
