Reson has been found:
In AMXX1.70 query_client_cvar() use a new function to query client cvar it is different with 1.60, this new function only be suported in Half-life 1 Dedicated Server build 3382 and client build 3382.

So, only when the server and client both use Cstrike1.6 build 3382 it can works.
When the server build is before 3382 , server report "Client CVAR querying is not enabled ..."
When the server build is 3382, server can work ,but if the client build is before 3382 client will exit and report this "Host_Error: UserMsg: Not Present on Client 58".
In MetaMod 1.19p28 sdk_util.h I find this:
#define QUERY_CLIENT_CVAR_VALUE (*g_engfuncs.pfnQueryClientCvarValue)
#define QUERY_CLIENT_CVAR_VALUE2 (*g_engfuncs.pfnQueryClientCvarValue2)

So should AMXX also give both query_client_cvar() and query_client_cvar2() to keep compatible backward?

Thanks for your work!

----------------------------------------------------------------------------
I have a plugin it uses query_client_cvar() function, it works fine in AMXX1.60, but when I upgrade to 1.70, It can not work.

This is the log:
L 03/09/2006 - 08:40:12: Client CVAR querying is not enabled - check MM version!
L 03/09/2006 - 08:40:12: [AMXX] Displaying debug trace (plugin "cvar_checker.amxx")

L 03/09/2006 - 08:40:12: [AMXX] [1] cvar_checker_203.sma::Task_DelayCvarCheck (line 226)

But, how to enable it?

I use CS1.6[Build 3329] and Metamod ver 1.19p28.

In 1.70 changelog, I found this:
[Updated cvarquery system to cvarquery2. This requires Metamod 1.19].

[VEN]

My guess: you have to wait for the official metamod.

[karlos]

do you have MM 1.19p28 ?

[Fanatiker]

same problem with me, even though i have the latest metamod ( 1.19 p28 )

[leon_008]

It included MetaMod 1.19p28

[Geesu]

I have various reports of this on the war3ft forums (war3ft uses this feature)

[PM]

Yup, my ios users said that cvarrules broke as well

[Fanatiker]

to fix up the problem warcraft3 FT is crashing the server, just remove the if query in the warcraft3ft.sma where the function is used. it's only once a time, a useless bot query head for line 377

[BAILOPAN]

what mod are you guys running this on.

I use Counter-Strike 1.6
