Error 500 in the frontend when a product is clicked to load product details

[Zrali]

Hi everyone;

I recently updated my Prestashop version to 1.7.8. After the updrage, everything works well except for the fact that there is an error 500 (crbug/1173575, non-JS module files deprecated.) when a product is being clicked to load product details.

I have tried several solutions to no avail. I will very much appreciate it if anyone can provide for me a lasting solution. Thanks

Whats the PHP  version? Friendly url's was turned off before upgrade, as now?

PHP version is 7.4; Friendly url wasn't turned off before upgrade. 

However, I changed the PHP version older versions and to recent versions but it didn't solve the problem.

When you go to this specific product on back office, save. If you press preview, same page error?

There is no relation between the 500 error and the "crbug/1173575, non-JS module files deprecated" message in your browser console. This is a PHP error not a javascript error.

You should look in the error log of your server. Also enable the debug mode of your shop.
