Hi! - I'm sorry for my bad english. 'Google Translate'

L 01/29/2018 - 01:54:26: [SM] Unable to load extension "left4downtown.ext": /home2/hizmet8914/left4dead2/addons/sourcemod/extensions/left4downtown.ext.2.l4d2.so: undefined symbol: g_pMemAlloc
L 01/29/2018 - 01:54:26: [SM] Failed to load plugin "nextmap.smx": Nextmap is incompatible with this game.
L 01/29/2018 - 01:54:26: [SM] Unable to load plugin "l4d2_tankswap.smx": Required extension "Left 4 Downtown" file("left4downtown.ext") not running

I did not get rid of these mistakes. What should I do? the new version then the old version etc. I tried to install only one l4d2_tankswap.smx plugin without installing any plugin, same error, same error. What should I do?
