some problems after hosting upgrade

Hi guys,

I don;t think this are hosting related, but maybe you guys might know that the problem is?

I’ve changed the wordpress hosting from php 4.x.x version to another hosting with php 5.2.x .

But after upgrade I’ve notice some php errors on Dashboard (wordpress 3.x admin interface).

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 491520 bytes) in /home/rezair/public_html/wordpress/wp-includes/class-simplepie.php on line 9907

At line 9907 in file class I have the following:
case ‘ebcdiccpbe’:

Any idea what went wrong during upgrade or how can I fix this ?

Many thanks!
