PageSpeed problem

[id design]

Hello, 

I have a problem on this site https://pepites-en-champagne.fr
Some modules don't work because of a bug that displays

VM1923 products:1 Uncaught ReferenceError: pagespeed is not defined
at HTMLImageElement.onload (VM1906 products:1) 

So I deleted all the modules that could use pagespeed, cleared the cache and even checked the database.

But the error message is still there.

Has anyone had this problem before?

Thanks in advance
