No options under "Choose a template" in Theme Editor

OpenCart Version 3.0.2.0

Hi, I just noticed that when I go to Design > Theme Editor, under the column of "Choose a template" , there's nothing displayed. I've included an image to show what I mean.


I don't know when this started happening, so I have no idea what could have caused it. I tried replacing my theme.twig file (in admin/controller/design) in case it was just a problem with the view, but there was no change. Any ideas would be greatly appreciated!

hit f12 on your browser and see if you see any errors in the javascript console.

Hi, I checked the console, there are no errors.

Any other suggestions?

Maybe a database issue with the installed theme, store ID.

You can see what the code is doing.
^ If this is returning an empty array then it's not reading the files.

Thanks for reply! Do you have any ideas how I could go about checking this?

I was able to find a solution, so I thought I would post it here in case anyone else has the same problem. The problem was with my config.php file - DIR_CATALOG had an incorrect path (had a dev/ folder from before I launched the site). Hope this helps someone else!
