Hello dear support before I update to 5.1.17 I have to ask are the changes done in theme files as I have created overrides with heavy modifications so I would like to check if I need to re-adjust them.

Second thing I noticed is:
If the item is not created in JlexReview and for example I visit search page and let us asume my search query is My Article after I click on search result I will be lead to that page but url will be: 

site.com/my-article?highlight=WyJ0ZXpnYSIsImJhcnMiLCJiYXIiLCJyZXN0YXVyYW50cyIsInJlc3RhdXJhbnQiXQ==

After that when I visit items page and open created Item My Article url will be:
/my-article?highlight=WyJ0ZXpnYSIsImJhcnMiLCJiYXIiLCJyZXN0YXVyYW50cyIsInJlc3RhdXJhbnQiXQ=

and after I correct it everything is ok afterwards.

Next thing is review module if I select Newest items and set it to display reviews from article category and publish it I will get broken webiste and following error:

I assume that this is because of me using php8.


Next thing if I select Area - Item in module and try to click on select button nothing happens.

Thank you!
