For example the images address on frontend website show this: https://takoda.shop/pub/media/logo/default/170xNxTakoda_met_Tijger_O_logo_kleuren_nieuw.png.pagespeed.ic._LOWhFVaw2.webp

It adds at the end: pagespeed.ic._LOWhFVaw2.webp

Never consciously changed anything by purpose

This causes possibly that some images on mobile view are not showing

Now also not in the browser look:

That is probably the reason

Only how to turn that off or fix this?

You find on google that it could be google pagespeed module, this module is not in the config.php file

Anyone got any clue what this could be and how to turn it off?

It can conflict with lazy load

The frontend is: www.takoda.shop
