I figured out my problem, I was talking to a php programer type person thingie, he suggested that i turn on custom sessions, Doing this fixed my banners...
I dont want to create a security hole on my site, so i am going to keep the banners off till i find an alternitive method of fixing this, or figure out why it stopped working in the first place...
for now i just turned off my banners When i first loaded XOOPS the banners did not workand i had to copy the banner php file, i am going to check that, maybe replace it...
