starting from some weeks, the theme editor is not loading the right side panel and I’m forced to work with the left side panel only. By reading on the Shopify guide here https://help.shopify.com/en/manual/online-store/themes/customizing-themes/edit, it looks like the right side panel is loaded automatically according to the screen resolution: my resolution is not changed and it is for sure larger than 1600 pixels wide.
I already tried with other browsers, I changed the screen resolution, I cleaned up the cookies…nothing changed: I can see and use only the left side panel.
Well it went up the Spotify support chain and they came back and said it’s “actually expected behavior” meaning they intentionally removed that feature and they may or may not consider bringing it back. Now, I can’t fathom any reason why they would intentionally take away a highly usable feature like that (“Um, let’s figure out a way to make editing pages harder for people”??). Instead, my suspicion is that when they rolled out the latest update last week, it got broken and they’re not sure how to fix it.
I just had the same thing happen to me and it appears to be a “zoom” issue. If you hold down the control button and use your center mouse wheel to “zoom out”, this fixed it for me. Hope this works for you too!
I spoke too soon. It didn’t give me additional options that I’m used to on the RH side. Instead it just brought part of the LH editing to the RH side, but nothing additional. Oh well, it was a good try. I hope Shopify gets this fixed. Its a real pain without it.
