error after upgrade

[golumtan4ik]

After updating from vbiletin 4.2 to 5.3.1
At the entrance to any post produces an error like in the screenshot
And in some posts it shows that the page does not exist
Although in the admin panel all posts are and they can be viewed there
There are more than 250 000 posts on the forum

How to solve this problem?
Can anyone help

Hmm, I don't see anything invalid in the SQL query. I executed it on mine and I didn't get any error.

4.2 The version was put once by other people
And they installed the site in the latin1 encoding, although the site itself was in Cyrillic and the database was in ut8
When updating in the config I expose latin1, the installation goes without errors
But then normally only the main page and admin panel work
And there are still errors: does not allow editing the content, produces an error 500, and the page does not

Tried to decode the base in normal utf8, like then the data in it is normal
But then it gives an error invalid route data
