I believe so from what my provider said has to do with the font, I'll pass his message here:
Good afternoon,
We've been testing this PrestaShop installation in debug mode and at the server level there are no errors or missing modules. The errors you indicate are at the JavaScript level and appear to be only related to the fonts used on the website. You should check this situation with the support team that develops the theme used.
Now if you can detect the error, I don't know, maybe in the admin panel you have javascript off and that is making the theme work well but I haven't tested that, maybe it's even that problem, but do some tests and disable some functions to see if the theme stop loading the products, because if you find where the error is so we can stop doing what I did, test it and then leave the comment here.
Now they say that the theme has an A grade on speed but my grade doesn't come out of D hahaha, that's not bad it has loading problems that takes a few milliseconds if it didn't take so long to load maybe a B grade would do it, besides the problem too it's in the index if you can tell me how to improve it share
