Hi! Some Questions / Errors?

[pikahlin]

Hello! It would be really convenient if someone responded ASAP, but I'll try and be patient!

I just recently installed MAS on the x10hosting site using the extremely helpful sticky on how to install MAS. It took me a couple tries, but I ended up successfully installing it..or so I thought? I got to Part Three of the Installation Wizard, and everything went well. However, when I try to log in or access the Admin Control Panel, it leads me to an error page.

It says "You will need to Log In to your installation of Mysidia Adoptables before you can access the Admin CP."
So when I try and log in it brings me to an error page:
"Fatal error: Class 'AppController' not found in /home/pawarupc/public_html/login.php on line 3"

And when I try to access the admin control panel, I can view the index page, however I can't edit/alter/view anything else.
"Strict Standards: Declaration of AdminSidebar::setDivision() should be compatible with Sidebar::setDivision(GUIComponent $module) in /home/pawarupc/public_html/classes/class_adminsidebar.php on line 18"
And then it says in bigger bolder letters :
"An error has occurred.
You do not have permission to access Admin Control Panel."

Hopefully this is an easy fix and I'm just new to this? Please post/contact me asap!
