global header does not print my variables

I'm not sure if this is related, but in your navbar template the $hizirbits is in a table tag but outside any <tr> or <td>. I realize that your plugin code adds those tags, but if you just use $hizirbits='test test test' as a test it might not be displayed. So you maybe could try $hizirbits= '<tr><td>test test test</td></tr>'. If that was the problem, then it could be that your query is failing.
