New problem! I have solved provious problem myself. In the admin configure file I forgot to change the 'admin' to the new admin name. The line that said (define('DIR_FS_ADMIN)...) .

I have uninstalled IH4 several times by removing the '//' before $uninstall='uninstall' in the init_ file. It even confirmed my uninstallation. But after re-uploading everything I ended up with a blank admin page.

Again, what is going wrong? Should i post some log files? Which ones?
