Solved Hanging URL

When submitting a reply in Kunena, I'm getting a hanging URL that is getting stuck and not resolving. Yet, when I click Cancel and check, the new post has been saved.

Can anyone make some suggestions as to what may cause this? There appear to be some email issues with the site. Just recently, i attempted to post a reply and got a bunch of SMTP errors. This is no longer happening but there are other global symptoms. I've asked my hosting company to look into it. Much appreciated. Configuration is attached.

Maybe you are having problems because you are using the K 1.7.2 Blue Eagle template and you have not updated Kunena Search plugin and Kunena Login module to the latest version?

I really do not know the answers about SMTP problems associated with your hosting company. That's something you need to discuss with the hosting company, I think.

Also, your version of Joomla is out of date and you should upgrade it.

As there has been no follow-up to this topic started nearly one month ago, we assume that these problems have now been resolved.
