URL structure customization doesn't work!
Hello. I have enabled the URL Structure setting to display topical addresses by ID. However, the search engine indexes pages by ID and title.
When a new topic is created, the search engine indexes one page with two options:
What could be the problem?
Google and other search engines should only display search result with site.com/category/title/ URL because the canonical URL of all your topics are using site.com/category/title/ type of URL. It doesn't matter what is the actual URL, search engines should always use the canonical meta tag. If you check the source of topic pages you'll see the wpForo SEO section with canonical URL.
In any case we're going to change the canonical URL corresponding to the topic URL structure to avoid such issues in the upcoming update.
