Can you share your filter here? Maybe that will give me a better idea of what’s happening.
Do you mean the display title in popular posts is changed only when viewing this specific page that you apply this filter to, or is it permanently altered to the new title?
I want to changed the Headline und Title of the page, which works with the following filter. But this also results in changing the titles in the sidebar widget of Koko popular posts. All 10 entries in the Koko-Widget have the name of the site.
The problem is not the page. The title is only changed on this page. That works.
But on this page, the changed title is also displayed in the sidebar in the Koko Analytics list of the most popular articles from place 1 to 10 (the URLs, on the other hand, remain correct in the Koko list).
Attached is a screenshot of the Koko Popular Posts Widget on that page. On all other pages and posts there is no problem.
