Shopify performance and not showing previews

Topic summary

Shopify store performance slowed and theme template previews were not displaying for the original poster on the same day; a screenshot was attached. No specific error messages were reported, and the issue appeared to affect only that user’s experience at the time of posting.

Suggested troubleshooting included: checking for any error prompts, clearing browser cache and cookies, restarting the browser, disabling extensions, and reviewing any recently uninstalled apps that might interfere with previews.

Outcome: By the next day, both performance and previews returned to normal without any changes made by the poster.

Status: Resolved. Root cause remains unknown; a responder suggested it might have been a temporary server-side issue. No confirmed broader incident or further action items emerged from the thread.

Hi,

Today I have noticed Shopify service low performance.
I was testing some of my pages and loading was quite slow today.

Also, I have noticed, that Shopify Theme pages does not show page previews.
Such issues appeared only today, did someone noticed similar problems?

Hello Avalanche,

Thanks for reaching out to the community!

Are you getting any particular errors when you try to preview the templates on the theme?

You can try clearing the cache files and cookies from the browser, which sometimes conflicts with the way the website is rendered on the browser. Thereafter, reboot your browser, and disable extensions, and check again if you can preview the templates now.

Also check if you’ve recently uninstalled any of the apps from your website, which might be causing this issue.

Not sure what happened, but performance and previews are working fine now!
Issue has been solved by itself during the night)

It might have been a server issue, but I’m glad it is resolved.
