How do i use my backup files back?

[benson]

Dear All,

please how do i use the files i backed up before upgrading because the upgrade has cause me nightmare to my project as pages are redirecting to one page when logged out with page ID changing and working well when logged in. (www.equipmart.net/index.php)

I will appreciate any cue to achieve this to make my site work as normal as before.

Thank you.

you must have made core changes?! just install your database from backup through your cpanel, and replied all of your old files
