errors concerning rendering

Hello, I am getting some errors when I click on certain menus such as sub menus in the user menu at the bottom of the page like the "site menu. Also I am getting errors in the forum sub menus such as my topics-I enclose 2 pics.Finally, I am having trouble updating the program and not sure why it won't work. I have tried both methods. Finally, I too have been subjected to attacks and I was hoping to disable my firewall for as short a period as possible. It is currently active for files.Hopefully you can let me know of you are available and I can disengage the firewall. Let me know if that is an issue
