So, here's the deal: Had to contact my server (A2 Hosting). They were really cool about the stuff. They said that it isn't SimplePortal itself, but the chat feature. He said something about only allowing 35 actions (concurrent I think is the word) going on at once; related them to mods being in play on the front end.
@SiNaN: THANK YOU for telling me about the debug deal! Man, that's all I needed (in the beginning it would have worked, but it devolved into a permanent 503 error though as I tried to reload SMF) to slide thru! G-d, I have tattooed that on my forehead!
I am going to play w/the chat deal, but am worried and would like some input. I will follow the thread and reply back and thanx to all once again!
Added: So, I switched the stuff as directed in the above referenced post to cure the chat and my site won't load. So, thanx to the debug deal I was able to access it and deactivate chat. Problem is definately chat. Bear in mind I only have two or three folks ever on at any one time.
Would appreciate it when a final fix (SMF or ya'll) is issued that some kind of mass mail go out so folks like me can use it.
Posted this on the SMF thread as I feel it needs to be cross referenced!
