Hi, I’ve had a Shopify store for the last several years. I have always used the Brooklyn theme. A few days ago, the format of my shop went ‘wonky’. Loading became very slow and the layout is off. I spend an hour talking to Shopify help and they tested several things. In the end they said that I had to update the Brooklyn Theme. When I look at the Brooklyn Theme, it seems that the last update was in 2021 and I have that update. Maybe I’m missing something and not finding more current updates? Also when I re-read the transcript, the agent said ‘use an updated theme’ so not sure if that means change to a complete other theme?
It’s strange that they suggest it’s the theme as I’ve had no problems with the site until 2 days ago. My thoughts are that it’s something else causing it?
Any ideas?
thanks
Hello @thebluehound ,
The Brooklyn theme is a deprecated Shopify theme, meaning it’s no longer maintained or updated by Shopify. Even though you’re using the latest version (from 2021), it’s not compatible with recent platform changes, which could be why your site suddenly started behaving strangely.
Shopify has been rolling out new performance and backend updates (e.g., changes to checkout, cart, metafields, app APIs), and old themes like Brooklyn can break when those changes aren’t supported in the theme’s code.
Switch to a modern Shopify 2.0 theme like:
Dawn (Free & flexible)
Craft, Refresh, or other free 2.0 themes
Or any premium theme that’s updated regularly
Rebuild your current store design using one of those themes — they’re much faster, have more customization options, and are built to work with the new Shopify features.
If you’re not ready to switch yet, temporarily:
Try disabling custom apps or custom code
Check for any recent app updates or additions that may have triggered the slowdown
The support agent probably meant “switch to an updated Shopify 2.0 theme”, not update Brooklyn — because Brooklyn won’t be getting updates anymore.
There could be main reason of why your theme is broken that you do the custom coding in theme. And when the theme is update to the new version then it remove the custom coding that you did in your theme files.
So, the solution is that you need to copy the code again and put it in the new update one version.
If you need help to update the theme then you can reach me by finding the details in the signature.
Thanks
Hi @thebluehound
The Brooklyn theme is no longer maintained by Shopify, with its last update in 2021. If your store suddenly became slow and the layout changed, it’s likely due to compatibility issues with Shopify’s newer platform updates, app conflicts, or broken third-party scripts—not necessarily something you did. When Shopify support said to “use an updated theme,” they likely meant switching to a newer, Online Store 2.0-compatible theme like Dawn, since Brooklyn is outdated. You can preview a fresh copy of Brooklyn to test, but moving to a modern theme is the more reliable long-term solution.

Please share your store link if possible.
Switching to a new theme all of a sudden can feel alienating for returning users who are used to the old layout and flow.
Brooklyn theme hasn’t been officially updated since Shopify phased it out for Online Store 2.0, so when support says “use an updated theme,” they likely mean switching to a newer one—but let’s check for other causes first like app conflicts or layout issues.

Thanks. I was hoping this wasn’t the case as am not looking forward to rebuilding a new shop.
