I have described all changes I have done to the site a couple of answers above, right before 'tonvies' last comment.
There's no difference between my site and the test version.
I am sorry Dude, but your comments are of no use to find a possible solution.
You say: "I looked at the source code and the main problem is that only one tab content is generated by wordpress. " So?
What am I supposed to do with that? How is that pertinent to finding a possible solution?
I have re-installed WP 3.1 twice
You say: " So even if you chose 4 pages in the backend only one tab/page is generated. I can only find a div called "fptab_content tab1" which indicates that tab2 and tab3, etc. were not generated by WP." And?
Nothing personal Dude, and thank you for trying to help, and will continue to appreciate it, but...
I have to say that at I am finding the available support for this theme the worst I have found for any theme I have ever bought from ThemeForest. In fact, I have never had so many issues (inherent, or created) with any other theme I have bought at ThemeForest.
The lack of of solution almost two weeks after posting the issue, makes the whole deal worst. It gives the impression that you are is reaching too much and far without the proper support strategy.
What I believe: If you would be using the ThemeForest website, and If this issue would have been posted in the ThemeForest website forum for the theme, I bet this would have been taken care of by now. Why? because most often than not, people make a decision about buying a theme or not, judging by the kind of issues people are finding and how fast are those issues being taken care of, but only for the last 2 or 3 pages of responses, (talking about the way TF shows comments) because we are all busy with a trillion things to do! So, if the answers seem right And if the theme looks as promising as this one, we are sold.
I love this theme, I still want to use it, but using "Yslow" and FireBug's pagespeed I have found so many bugs and issues with this theme, that... like these:
So much unused CSS for the home page: 45.8% of CSS (estimated 26.4kB of 57.7kB) is not used by the current page.
and so many very inefficient rules: http://sandiego-webmaster.com/wp-content/themes/avisio/style.css has 18 very inefficient rules, 65 inefficient rules, and 9 potentially inefficient uses of :hover out of 269 total rules."
that I am starting to wonder if I am really going to be able to keep it. And I DO want to keep using it. I still believe that the theme's concept is The best ever.
