Why is Debutify 3.0 slowing down my page speed?

Hello, I just upgraded to Debutify 3.0, and it looks awesome. The problem is my page speed has collapsed, and some pages won’t even load. . I’ve deleted all of the apps that I don’t need. Am I the only one who has this issue? I didn’t have it with the other version. I checked the console and found this error. Could it be the problem?

It could be, but that one might be hard to investigate because it appears to be coming from a minified theme file. Since it’s theme related, I would contact the developer.

But first I would read your theme files and clean up any old app code (if you haven’t yet). When you delete an app, it loses access to your store instantly, so any code that it added to your theme will remain there.

We see this pretty often, where old app code is leftover in theme files. The most common places to look are theme.liquid, product.liquid (and it’s included snippets), cart.liquid (and it’s included snippets). 90% of old app code we find is in those 3 areas.

When you upgrade to a new theme, usually it overwrites theme customizations, so if you had your store optimized in the past it’s possible those optimizations were overwritten.

You can run your site through the Shopify Analyzer to see if there are any optimization issues with the theme or images. The Shopify Analyzer is a free tool my team built for the community. It’s geared specifically for Shopify sites and includes resources to explain issues and how to fix them.
