Apple-touch-icon only working partially

[Scully]

I tried hours to figure out why the apple-touch-icon does not work when adding a normal bookmark into favorites.

There apprease the famous "question mark" instead of the icon.

 

However it works finde when saved to home screen.

 

Prestashop Version 1.6.1.13.

 

There are no 404 messages in the logfile related to the icons.

 

It used to work both sides with prestashop 1.5.6. A fresh and clean install with 1.6.1.13 results in the same behavior as on our installation. It does not seem to be a specific problem with our installation.

 

I also checked the HTML source from a website with an apple-touch-icon plugin. There, the images are saved under the modules path instead of root. I also tried this with no success.

 

Any help is appreciated.

Thanks. Scully
