I have a very old signup popup on my store that I cannot get rid of. I have looked everywhere for it in the theme file and it's nowhere to be found. I have contacted Shopify who advised me to contact Mailchimp. I did try to do this but they don't offer any email support to free plans - only a chatbot. I have no idea what to try next, would anybody please be able to guide me in the right direction? I have included a screenshot of the popup. www.flowerandtwignursery.com.au
If it's external, it's a bit tougher because you don't know the name of the .js file that gets fetched. You are looking for something like:
that hopefully includes the term in it.
In any case, there might be HTML code that you can find by searching for the term (a popup's code would be at the start or end of the body tag).
The truth is that several email popup apps leave snippets in the theme when you uninstall them, that's why you might want to take a backup of the theme before installing one.
