Problem with Product Images Not Displaying on Category Page in OpenCart

Hi support team,

I'm currently facing an issue on my OpenCart store (version 3.0.3.8) where product images are not displaying properly on the category pages. The product thumbnails are just showing as broken image icons, although the images are visible in the product edit section in the admin panel and also not showing on official site.

I’m using a custom theme (Fastor), and I’ve tried clearing the cache, regenerating the image thumbnails, and re-uploading the product images, but nothing has worked so far.

Is this a theme issue, a permissions problem, or something else I might be missing?

Would appreciate any help on how to fix this.

Thanks!
