Try disabling your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

but know my portal mod is nat working i am getting this

Fatal error: Call to undefined function print_portal_output() in /home1/xtremeg2/public_html/G.F.X/portal.php on line 46

Since when you disabled the plugins, the problem went away, that means that one of your plugins is causing the problem. You may turn them back on, one-by-one, and check after each to see if the problem is back. That should help you figure out which modification is causing the problem.
