The link problem seems to be with ANY editor used with the content module. I have now tried Koivi, fck,ck,tinymce and a few others. It seems that the module is forcing it's url in front of the actual url of the link.
The only other module that we are using that requires a wysiwug is news and it functions properly with any editor. Links are given as typed.
As for tinymce, the main site background ONLY show up during admin. When page is viewed everything is fine. I have not touched the CSS's for the site at all. The only thing I did was replace the header image with mine by renaming mine to the one the author used to build the theme.
Experiment: I remove the background image for the theme and the problem with tinymce went away. But I really don't want to do that as it is what makes the site.
I also cannot embed any flash video as all the editors mess up the code by adding those lines, mostly invisibe to the front page but they're there none the less. Funny thing is this is my 4th XOOPS site but the first beyond 2.14. It was no problem adding flash to any page, now it is.
They all work flawlessly. 1 for over 4 years without a complaint from the owners. I have had to do very little to maintain these older sites.
