[Plugin: Special Recent Posts] Incompatibility with Mingle plugin

Hi!
When I install Mingle plugin, as a result Special Recent Posts plugin doesn’t work properly. I got this error message:
“Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 10368 bytes”
Is there an incompatibility? Am I using to many plugins?
Thank you for any help!
Rocco 🙂
