I ran debug popup and these are the errors. I did nothing but install the modules and work on the admin panel in Xoops. I did no php modifying (don't know how), etc. I hope this is the right place to post. Not sure if it is an install problem, module problem or...

the notices you can ignore, they won't harm anything as they are just informative notices.

the warnings mean there's a problem with those modules where the notices come from..

mainly you have problems with entdirectory module & also friendfinder module. if you can i'd check the authors websites who wrote those modules, as they will know more about them, also there could be updates released..

Your error of _MI_FUNGAMES_NAME - assumed '_MI_FUNGAMES_NAME' is also fixed just as it says...by adding the ' ' you can fix that
