wicketywak on "no visual or text ?"

Hi everyone
i am having issues with my newly installed site. i can edit all pages except teh home page of my site. the visual or text box shows nothing. even when i hit to toggle the menu or help keys nothing happens. even the box at top with the styles keyboard etc is not there?
Upon signing in i get this error-
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 1966080 bytes) in /home/wicketyw/public_html/wp-includes/SimplePie/Item.php on line 2736
could the home page editing not be loading up because of this error?
i am only new to this :)
netregistry they put the site up for me, used this program and designed it. now they dont know how to fix this issue as well. funny as they should know how to fix bugs when they are the professionals i though .
any help really appreciated thank you :)
