Since I upgraded I've noticed a few 404 errors popping up and it seems that yahoo is incorrectly indexing my pages.

Yahoo index's my page as hxxp:// www.mywebsite.com/englishforum/english-i...and-vocabulary./what is ESL, english, second, language

The correct page is hxxp://www.mywebsite.com/englishforum/english-i...second-language.html

Does anyone know what is going on? How can I fix this?

I am running Kunena 1.5.8 on joomla 1.5.15 with artio 3.5.4
and plugins
AlphaContent 2.0.1
Content 2.0.13 <<This reads higher than the newest version!!!
Glossary 2.0.1
Kunena Forum 2.0.5
User 2.0.3

Thanks in advance.

I've substituted my real website name with mywebsite.com
