Does not load product thumbnail image

Hello.
Could you help me with an error, when I publish a new product, the thumbnail image does not load. I have already reinstalled several times and it still gives me that error.

Thank you

Have you tried opening your webpage using Google Chrome?
 Do you have any errors in developer console (F12 -> Console, in Chrome)?

Hello, thanks for answering.

In Google Chrome I get this in the console

So, there is a problem.  Images are linked through the HTTP instead of HTTPS. 
Try following:
Settings -> Images -> Clear Thumbnails Cache
Settings -> Advanced -> Clear System Cache
After that try CTRL+F5 in Google Chrome.

It doesn't work, the thumbnails still don't load

Delete everything from cache folder (public_html/cache)

It doesn't work

Are you on some proxy solution? It looks like LiteCart fails to detect you are loading the page over HTTPS. This is done by $_SERVER['HTTPS']. Is this Apache, Nginx or something else?

LiteCart attempts to link resources to the same port and protocol identified by PHP.

This is not a cache issue.

Hello, it is already working well, the problem was with the SSL certificate, I installed another certificate and it worked correctly. Thank you

That simple? 😄

Can you please explain what was different in the other SSL and what was blocking the thumbnails?

@303boost SSL errors should be visible in the F12 console. If it's a PHP malfunction see logs/errors.log.
