Page not found error

Hello

I did my best to find by myself the fix for the problems i have, and i didnt find any solution, so i need your advice .
Just made the update from 1.5.4 to latest opencart 3.x , i got the journal theme, i know there are many negative things about this theme, but i like the design and decided to give a shot. The problem i have:
1. At random point i get "Page not found" with continue button that will redirect me to home. I dont know why this happen, i try with cache on, off, nothing help.
2 Some of products can not complete the check out, as i saw the checkout page freeze when modify the quantity or try to remove the products, it get my action only if i hit browser refresh button. Also i can not complete the check out process and place the order. For example on mozila i can not complete the order for this product: http://www.visolishop.ro/pompa-submersi ... isoli.html . It can be added to cart, then i can see the cart, at this point i can make the cart modification, but after login/register page, it freeze.
Any advice will be thankful

This is the only one error i have in error log file: 2020-01-27 13:46:57 - PHP Warning: unlink(/home/visolishop/storage/cache/cache.catalog.language.1580136396): No such file or directory in /home/visolishop/public_html/system/library/cache/file.php on line 68

thx, i did the modification, no error logs now, but the problem still there

Yes, because that fix was for storage/cache/cache.catalog.language.1580136396): No such file or directory in

For you problem check the .htaccess for mistakes
Or SEO for products.

I dont think this is a seo url issue, because i disabled seo module, and the problem i have with the cart are the same. also made the change recommended on cart.php but didnt fix it

You can post on Commercial section and paid someone to look and fix
