ultimateuser on "Fatal error: Allowed memory size exhausted"

I'm running WP 3.6 with BP 1.8

I get the following error:

Fatal error: Allowed memory size of 94371840 bytes exhausted (tried to allocate 1966080 bytes) in /home/home/domain.com/wp-includes/SimplePie/Item.php on line 2736

I already tried the following:
- Increase memory through wp-config
- Increase memory through php.ini
- Disabling plugins

However the error doesn't wanna go away.

Any advice?

Thanks
