I have a strange issue that I'm not able to fix out regarding tags.

Here is an example. When viewing this page:
www.jamesallenlibrary.com/authors/james-allen/mastery-of-destiny/deeds-character-and-destiny

It displays correctly and the menu item "Read Online" is highlighted, which is fine. However, when you click on a tag (which I have renamed to "Topics"), some tags are causing an issue.

Clicking on "The Mastery of Destiny" takes you to this page and has the correct page title:
www.jamesallenlibrary.com/tag/the-mastery-of-destiny

Clicking on "Deeds" takes you to this page and has the incorrect page title. It has the title from the "Listen Online" menu item and the "Listen Online" menu item is highlighted.
www.jamesallenlibrary.com/tag/deeds

I'm not sure why tags would be showing up under that menu item. If I turn breadcrumbs on, "Listen Online" shows in the path as well.

I'm using SH404SEF. I've spent some time with this issue and can't figure out what is causing it. Any ideas?

Can you try purging your URLs?
Are you using the redirect component?

I just tried purging the URLs and it didn't fix the issue.

I'm not using the redirect component.

Thanks!

I figured it out, kind of. After loading the K2 SH404SEF plugin (didn't realize there was one), then flushing the cache and everything, it's fixed!

Nice to hear that the issue has been resolved Jared :)
