The list of products disappears

[pr1z]

I guys,

 

I'm currently facing an issue on my website.

When I browse my products into a dedicated category, it seems that at some point, the product list disappears.

When I open the Console from the Browser Investigator, here is what I have:

 

Uncaught TypeError: a.getElementsByClassName is not a function
    at f.doSync (wow.min.js:2)
    at f.<anonymous> (wow.min.js:2)
    at MutationObserver.<anonymous> (wow.min.js:2)

 

f.doSync @ wow.min.js:2
(anonymous) @ wow.min.js:2
(anonymous) @ wow.min.js:2
childList (async)

reloadContent @ blocklayered.js:481
(anonymous) @ blocklayered.js:295
dispatch @ jquery-1.11.0.min.js:3
r.handle @ jquery-1.11.0.min.js:3

 

I red that it could be relative to some additional modules.

But before trying this way, I'd like to have some help from the community.

I attached a screenshot to explain my topic.

Thanks in advance.
