Well, then this is another duplicate and not the same as your website, as those steps solve the issue locally.
Note, there is as well a Post with the corrupted title, maybe that as well needs to be updated.
Any broken special characters in your version of the database backup are, could also be due to the export with Duplicator?
Sure, but then why would it work locally recreating those?
On the access provided to me, I see in fact WAY fewer content templates than on the duplicate I received!
As well they seem not corrupt on your install.
(Have you edited those already, I assume.)
I also see this is a Multisite which is different from my local install
hidden link is a 404 - I cannot test the issue online.
This Page here seems to hold the view now?
hidden link
However, that view is not the same as I see locally.
It does not have any of the mentioned paginations, for example.
I can make the tests online if you allow.
I will need to trash the templates, and eventually make more tests, if that doesn't work.
Note that locally nothing else but fixing the corruption solves this issue.
If you allow, I can make the tests online after you outline where exactly I will have to check if it works, and I am allowed to edit the site in any way (I would suggest a good backup if this is a live site or better a testing site)
Then I can do this online.
