The index page shown in the image is the default index page of Elgg with walled-garden option ("Restrict pages to logged in users") enabled. If the theme plugin shows this index page (and also gives errors) it might be that this theme is simply not working with the walled-garden mode enabled. Try it with the walled-garden option in the advanced site settings disabled. If the theme works then, it would have to be modified/updated to also work in walled-garden mode.
It seems that the Easytheme2 plugin has some problem when you decide to add (or even more so remove) content from the text boxes to be displayed at the top of the pages. Have you any content displayed in the longtext input for the right box in the Easytheme plugin settings? Does it work to enter some text and save the changes (i.e. does textright.php get created at /home/pb268ho5/public_html/rs/data/easytheme2/textright.php then)? If not, you might need to create the file yourself at this location with the content of the file formatted as html as it should be displayed on the site then.
Another possibility would be to override views/default/page/elements/header.php. If you don't want anything from header.php displayed, you could override it with a modified version that is empty beside the initial <?php line.
If the modification seems to have no effect, you might need to flush the cache in the admin area. And it might be that some other plugin (theme) overrides the view(s), too. So, you would have to make sure that your plugin that contains the modified views is placed lower in the plugin list.
