Prestashop 1.7 Problem with related products on product page

[mmlr.m90]

I am new to Prestashop and I am doing some fixes on an existing page, I having a problem with the related products that appear in each the product page, I am using the Products from the same category module. The problem is that I'm not able to see the related problems, if I inspect the HTML I think the content is there but I'm not able to see it in the page

I tried to unnistall and install the module again, but result is the same.

I can see that the error is:

Uncaught ReferenceError: baseDir is not defined at HTMLDocument.

<anonymous> (postabcateslider.js:9)

at u (core.js:39) at Object.fireWith [as resolveWith] (core.js:39) at Function.ready (core.js:39) at HTMLDocument.H (core.js:39)

Can anyone help?

Thanks in advance
