It turned out that after I deleted two unused templates I had installed to play with once upon a time, but had turned off, it started to work perfectly!
I had tried to delete these template before, but kept getting an error that I couldn't remove the last template. I found a way to delete them manually and several issues I had experienced, became resolved!
Now, I'm really loving your software for our community site!

Best 'net regards,
