What is your site?
What version?
What mod did you try to install?
Did you get an error during the installation of the mod?
Did you take a backup before you installed the mod? (If not, do remember to do that next time)

Package manager makes a backup before it installs a mod.  Look in /Packages/backups.  Download, unzip, upload to forum root.
