Error: Materials...

[[rev]=Gen*=JediMasterAlex]

Everytime i start up my server i recieve a few errors:
Error: Materials "sprites/bubble" : proxy "animated texture" not found!
Error: Material "models/props/cs_office/screen" : proxy "animated texture" not found!
Unknown command "mani_spawnpoints_mode"
Unknown command "mani_spawnpoints_radius_limit"
Unknown command "mani_spray_tag_block_mode"
Unknown command "mani_spray_tag_block_message"
Unknown command "mani_spray_tag_slap_damage"
Unknown command "mani_admingravity_anonymous"
WARNING: Couldn't find server variable: mani_css_bounty
I don't think any of these cause a serious problem, but i'd still like to know what they are, and how to fix them if possible.

those commands/vars simply dont exist so you will ahve to delete them from the cfg or anything you're executing.
