3.0.3.7 bug? No thumb after selecting image in product or slider.

Hi,

On 3 different shops with all 3 standard OC themes and version 3.0.3.7 i got the same annoying bug every time: when selecting an image for a product or banner (or whatsoever), after selecting one, i DON'T see a thumb. Only AFTER saving the thumb shows up.

All settings are good, chmods are all 0777, but...no thumb.

How to solve? See attachment.

Kind regards,

Kec

What version of PHP? Have you checked both the OpenCart and PHP error logs? Do you have any extensions installed?

hi, Thank you for your respond.

• php 7.4.33
  no errors or whatsoever, not in adminlogs, not in serverlogs
  sure loads of extensions, but none of them are regarding images

My first opinion is that it looks like some cache-related issue..

Try disabling your browser cache. You can do this under the Network tab in its developer tool.

If that helps setting cache control headers is a good idea.
