1. I login and re-installed the module on home page (restored the template) and it seems the error disapeared.

2. For considering about the slidedown panel when login I would suggest a separate module. Since from functionality point of view, this part is not belong to the AdvancedLogin module and either we can do a SkinObject or more flexibly do a module. Again, I think it is a good idea.
