Question [Q] unfortunately the process com.android.phone has stopped (slimRom)

OK, so, I'm not to experienced with all of this but for the past few months my phone has had an error message pop up some times that says "unfortunately the process com.android.phone has stopped" when I am trying to send a text. I have no idea what could be causing it and I don't see any help for this topic any where. Some similar problems all you have to do it wipe the cache and the dalvik cache and it that fixes it. I tried this and it seems to work for a little under a week and then I have the problem again or it doesn't help at all. I was just wondering if you guys had any suggestions for this or any thing. I would even be open to switching roms as long as they have a dark thing like slimbean. Any help would be greatly appreciated.
