Hey @Sagar_Moriya , thanks for sharing the info here. Just as some quick troubleshooting, are you able to access other parts of the admin normally or does this just happen on the themes page?

If you’re open to sharing the myshopify.com URL for the shop and it’s attached to the same email you use to login to your community account here I can take a look into this further for sure as well.

I have the same issue, I can’t load Themes and Preferences pages, and same for the Editor. I noticed this since my Shopify app deep link stopped working

Hey @fafifox - thanks for reaching out. If you’re open to sharing your myshopify.com URL for your shop I can definitely take a look. Let me know if you’d prefer to DM as well and I can set that up on my end.

Just mentioning I’ve been seeing the same thing for the past week or two. Latest Chrome on Windows.

Hey @Will_J_Broderick - thanks for flagging this.

Just to narrow this down, are you mostly seeing the blank page when opening the theme editor or Themes page from a direct URL/new tab, or does it also happen when navigating through Shopify admin > Online Store > Themes?

We’ve seen a few similar reports where a refresh or opening the editor through the Online Store navigation works as a temporary workaround, but I’d like to grab a bit more detail here. If you’re open to it, I can set up a DM so we can get the myshopify.com domain, the exact URL path that’s blanking, and a screenshot of any stalled Console/Network requests.

I’ll keep checking on this on our end too.

Hey @Alan_G - more than happy to DM, share Network tab data & flows/videos, etc.

Your suggestion of hitting admin home, then OS, did seem to get it working again. Now I’m opening /themes/ in a new tab and it’s OK. I will continue tinkering until it fails again.

Glad to hear that helped @Will_Broderick - I’ll DM you for that other info in just a moment here.
