Fatal error: Allowed memory size of … bytes exhausted

Hi,

I’m building a blog that has alot of products posted from Amazon and the memory size is exceeding the limit…only one problem. I don’t know how to fix it. I already had this problem with my sitemap generator, but manually increased the memory limit and it worked. Still in my Dashboard, though, I’m receiving two error messages. The first is under the Plugins box which reads:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 11976 bytes) in /hxxx6/cxxxxxx3/public_html/sxxxxxxxxxxxxxs/wp-includes/functions.php on line 959

The second is in the WordPress Development Blog box which reads:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 64 bytes) in /hxxx6/cxxxxxx3/public_html/sxxxxxxxxxxxxxs/wp-includes/class-simplepie.php on line 13155

Thanks in advance for any suggestions!
