Congratulations, you are my new best friend

For some reason I have not been able to determine, my system module button is disappearing and I cannot get into my system module anymore to reset prefrences, etc...

The first time this happened, admittedly enough I was in the modules menu and I assumed I had done something wrong, but this time I was adding forums when it happened. Can someone please tell me what is going on and more importantly, how to fix it. I don't want to have to start over again.

I am running XOOPS 2.0.5.2. I have not had any major problems until now, and I am 99.9% sure I set everything up correctly, and the only modules I have installed are the core modules. HELP!!!

Edit: I just realised, maybe this should be in the bugs forum?? Sorry if it should...

I have tried both versions of the module and in both I cannot reset preferences. As soon as I do, it says configuration saved, but it does not actually save my prefrences, it goes back to the same values, and I cannot figure out why it is doing this. I have not seen any other people posting about this problem, so it must have something to do with my setup, though I cannot imagine what is set up wrong that would cause this.

I want to turn expiration off, if there no way to do this?

Okay I want to put a custom block on my front page and I want to make it visible to anonymous viewers but I can't. I have tried several different ways and I was wondering if anyone here knew how to make a specific block visible to a specific group of people, because I could not change it myself.
