Elementor Menu Error

Hello,

For some reason, there is an error appearing in my website footer, but *only* on individual product pages in our online shop (at flutronix.com). This happens on multiple browsers and on the mobile site as well, but I can’t seem to figure out how to fix it? Again, the error does not appear in the same footer on any of the other pages, including the main store page and even the store cart/checkout page, only on the individual product pages in our online shop. Any help would be much appreciated.

Best,
Nathalie
