Fatal Error Help!

I got a fatal error but the site still works but is slow in loading. How do I address this? I think maybe im running too many plugins at one time?

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 7680 bytes) in /home1/pacecrea/public_html/thatsredonkulous/wp-includes/kses.php(1006) : runtime-created function on line 1

What can I do for this? My hosting is unlimited everything so memory shouldn’t be an issue. Thanks
