Find
...addons/metamod.vdf file and move file out from
...addons/ folder.
Reboot server. Server should now run without MM:S and SM (server command
plugin_print, meta version, sm version)
Test, change level to normal, official TF2 map (ex.
cp_dustbowl).
Does your server crash, without mods, when you enter in game?
If crash not happen
Download latest MM:S and SM mods.
https://www.sourcemm.net/downloads.php?branch=stable
https://www.sourcemod.net/downloads.php?branch=stable
Upgrade MM:S by uploading all files to server, overwriting all files.
Upgrade SM by uploading these folders, files included:
...addons\sourcemod\bin
...addons\sourcemod\extensions
...addons\sourcemod\gamedata
...addons\sourcemod\plugins
...addons\sourcemod\translations
There should be new metamod.vdf file in
...addons/ folder, if not then move old one back.
Reboot server, first time.
Let server run about 15minutes, SM maybe download newest gamedata files.
Reboot server, second time.
Check loaded mods by using server commands:
plugin_print
meta list
sm exts list
sm plugins list
Change level again, to normal official TF2 map, enter in game.
Does server crash ?
--------------------------------------
If server still crash
rename folder
...addons\sourcemod\plugins to else, ex.
...addons\sourcemod\-plugins
Reboot server, change level to normal map, join in game.
If crash not happen any more, it's one of SM plugins what cause it.
Rename plugins folder back and now you need load one SM plugin at time and test every map change, which plugin cause it.
-----------------------------------------------
If server crash without SM plugins, try unload any MetaMod:Source plugins (not the SourceMod).
Need reboot server when move, disable MM:S plugin, just to make sure.
