What the meaning of ( Loading the code for the Product Page page. To debug this code, open cb4u.js in Developer Tools. ) and How can I do it

This message is just an informational message. The “strange” file name, cb4u.js, is for debugging the code in the browser’s developers tools console.

thank you, Can you tell me what the solution is ?

@waleedtaleb There is no “solution” since this is the way it’s supposed to work. This message always comes up for a page.

@yisrael-wix but related products don’t work why?

@waleedtaleb What do you mean? What isn’t working?

@yisrael-wix I mean I tried to add a related product but it doesn’t work why?
