How To Re-Enable Addons For Versus
By Xanaguy
Back in November 2018, Valve has released an update that disabled all addons in all versus game-modes (except for custom campaigns) and in every Official Dedicated server they run. This is a huge problem for custom versus mutations primarily because it counts as an addon, which causes crashes for Community Dedicated servers and an Engine Error CTD when starting a Local Server (due to "reaching the VPK limit" when this is obviously not the case). Fortunately, this guide will explain how to remedy the restriction.

- (Local Servers) Locate and open "addonconfig.cfg" in "Left 4 Dead 2/left4dead2/cfg".

- (Community Dedicated Servers) Locate and open "addonconfig.cfg" in "<your server directory>/left4dead2/cfg"

- Change all "RestrictAddons" values to 0

- Save changes and enjoy hosting your local versus server.

While official dedicated servers run by valve will never have this change, community official dedicated servers can. Of course, you can always just host a local server.

It's still work fine, made everything like in this guide and now all my mods work on local versus server (which been restricted before) :steamthumbsup:

This might be outdated since everytime I’ve loaded up a singleplayer vs just for achievements, it boots me back to the main menu.

Though if this is not the case for your side then it’s probably Vanilia+ main menu that’s the problem.

It doesn't seem to work, no custom material shows up in my hosted local games. Anyone could care to help?

Thank you so much for the guide! I thought I just had to set sv_pure 0 and sv_consistency 0.

Used this guide once, can't believe I use it again twice. Thanks again one more time. I just install the game on new PC and wondering what am i missing to enable the mods. :delicousbrew:
