I’ve been getting this error on my store occasionally when a product is selected.
“There was a problem loading this website
Try refreshing the page.
If the site still doesn’t load, please try again in a few minutes.
Refresh Page”
Refreshing the page doesn’t help. It only started happening yesterday. I removed “Blockify” I had installed the app yesterday, but had not set it up. App is uninstalled, but I’m still getting the error, when I select the second or third item to be put in the shopping cart. Scary. It’s going to cost me customers.
As the problem began after you installed Blockify, even after uninstalling it, some remaining code or settings may still be influencing your store.
These are a few things you can do:
- Clear Cache – Attempt clearing your browser cache or try testing in incognito mode to determine if the problem continues.
- Verify Theme Code – There are apps that leave traces in your theme files. You can try going to Online Store > Themes > Edit Code and see if there are any
- Remaining Blockify-related scripts in cart.liquid or theme.liquid.
- Turn Off Interfering Apps – If there are other apps processing the cart or checkout, attempt turning them off temporarily to check for an interference.
- Check Console Errors – Open DevTools (F12 or Ctrl+Shift+I in Chrome) and examine the Console and Network tabs for errors when adding a product to cart.
- Test on Another Theme – Test switching to a default Shopify theme such as Dawn to determine whether the issue continues.
- Reach Out to Shopify Support – As an absolute last resort, Shopify support can review whether there are server-side issues or residual app-related issues.
The ““second or third item”” detail is actually a useful clue - that kind of pattern usually points to something in the cart’s event handling rather than a general page problem, so focus your testing there specifically.
One thing not yet covered: check if your theme has a revision history. In Online Store > Themes, some themes save previous versions, and you might be able to roll back to a snapshot from before the app was installed. If that option exists for your theme, it’s a much cleaner fix than manually hunting through code for leftover snippets.
When you open DevTools, the Network tab is more useful here than the Console. Filter it to XHR/Fetch requests and watch for any failed or blocked calls that fire when that second item gets added to the cart. The ““There was a problem loading this website”” message is a generic browser/CDN-level wrapper - the actual underlying error almost always shows up as a failed network request (403, 429, or a blocked script call) rather than in the Console.
Also worth keeping in mind: it might not be Blockify-related at all. Shopify occasionally has intermittent AJAX cart issues that affect certain stores, and the timing of the install could just be a coincidence. Cross-checking shopifystatus.com for any incidents around March 18 would at least rule that out.
If you do find leftover scripts in your theme files and aren’t sure which ones are safe to remove, Blockify’s support team should be able to confirm exactly what code was injected during install.
