You tried to disable the right click on the WHOLE website, or on images? (To protect them from being right-click and ‘‘Saved as’’ ?
If so, wix have a thing called ‘‘Right click protect’’ (if you don’t want any copyright text, just set the opacity at 0%)
It do not work inside repeaters, but… a simple square with 0% opacity on top of your image do the same work!
If the code is suppose to disable the right click inside the whole website, than i cannot help you with that sorry !
