urbannews:

did you install wordpress by yourself or you are using the one provided by AlterVista?

I have the same error at upgrading the wordpress to version 3.5

it's a problem of PHP memory limit. Maybe your aggregator has to parse large feeds.
try to add this on your htaccess file:

Code:

---

php_value memory_limit 128M

---

128M is the max limit allowed.
