I've been tripped up by that email signup form that's in the bottom footer of the site too!

I think that if you click the "search" button/link next to the search field rather than hitting the enter key on the keyboard, it processes the correct form and allows you to use the search function correctly.

Hopefully that helps you till it's worked on.

It is what I do, I never use the enter key to submit.
Have you tried? Search function work fine for you?

This is a classic case of two third-party modules conflicting with each other. I've already contacted one of the vendors months ago, but the only possible fixes would require some adjustments to the website itself by those of us with access. Unfortunately, my hands are tied right now trying to close some business before the end of the year, so I can't resolve this myself anytime soon.

Please know in the meantime, that we all are encountering this same annoyance and will definitely resolve the issue as soon as possible. Sorry. :(

As for the search results, I'm not sure about that. We're currently using YAF for DNN. I know it has an upgrade available, but I'm not sure if that would resolve the issue. Any ideas or suggestions are appreciated.

I don't know Yaf for DNN. Have you try to see if some scheluded job is disabled. Any error in event log?
If there is a problem that needs to be fixed you can try to open an issue on github!
