I have noticed I cannot get the inbox to load for 1.7. I first thought it was because I had so many friends or messages so I made a new profile with no friends and I added 2 friends and messaged them and went to load my inbox and still cannot load it.
well then what good is this plugin if I don't have enough memory on an average server? Look oxwall is missing out on money or someone is you could have a service for this plugin that stores and loads messages for a monthly charge.
