It was theme related, it was linking thumbnails to the posts. Got it figured out. Thank you for pointing right direction!
Thank you, the last one did change my test product without image. Other’s didn’t, so it looks like i have to start digging it from the theme’s side.
Sorry about that! I changed the lines in function, but it still keeps links in images.
I made quick example page, since real product page is behind login.
Edited links away.
I have those remove_action lines in child themes function.php.
Thank you, I have tried this one already but it doesn’t remove links from those thumbnails. Other links will go away with this one tho.
