Often in a prestashop that I manage it happens that the ps_searchbar plugin does not work correctly the usual drop-down menu with product thumbnails (see attach file).
The drop-down menu does not appear on the Firefox or Edge browser.
On the Chrome browser the drop-down menu appears but it does not give the possibility to click on the products (clicking on the products displayed in the drop-down menu takes you nowhere).
By cleaning the browser cash, the drop-down menu starts working again for 2 or 3 searches, then the problem returns.
The problem doesn't seem to exist if I reach the site from a smartphone.
In a local copy of the same prestashop the problem does not arise. The most visible difference is that the local copy is updated to version 1.7.8.9, while the online version has recently been updated to version 1.7.8.10.
In another prestashop that I manage the problem does not arise, this site il updated to version 1.7.8.8.
Maybe there are other differences that but I can't see it at the moment.
Has anyone already encountered this type of problem and could tell me a possible solution?
