Line numbers would help greatly, but it doesn't look like that would compile at all unfortunately. You're missing a definition and assignment for g_hPubBlock. FindConVar isn't guaranteed to succeed either, so maybe it's that.

FIXED


PHP Code:
GetConVarBool(g_hVanillaBlock) 
Replace (This is a Integer, not a Boolean.)
PHP Code:
GetConVarInt(g_hVanillaBlock) 
-------------------------------------------
PHP Code:
GetConVarBool(g_hReady) 
Replace (This is a Integer, not a Boolean.)
PHP Code:
GetConVarInt(g_hReady) 
-------------------------------------------
PHP Code:
GetConVarBool(g_hPubBlock) 
Change (Because this is not a ConVar, just a boolean.

PHP Code:
GetConVarInt(g_hReady) 
We do not have control over other plugin's variables, make sure this variable is an integer and not a boolean.

It doesn't matter. All ConVars are strings and GetConVarInt/Bool just changes it into a format that you want/expect. In this case, you'd except this ConVar to be a boolean. The issue could likely be that l4d_ready_enabled doesn't exist at the moment this plugin starts, as that ConVar comes from another plugin. I'd recommend searching for the ConVar OnConfigsExecuted instead of OnPluginStart, as well as checking if FindConVar returns INVALID_HANDLE for when the ConVar still can't be found.

l4d_ready_enabled exist on OnPluginStart (return 0).

made ​​some changes and if I have a problem, I'll look for OnConfigsExecuted

I don't see a solution. I don't even know what the problem caused.
