Luckily I added a define to enable/disable the Okapi method in the sma.

L 06/29/2016 - 18:19:07: [static_cfg_restoration.amxx] [STATIC] The static file was loaded and its cvars applied correctly.
L 06/29/2016 - 18:19:07: [static_cfg_restoration.amxx] [STATIC] amx_static_enforce is 1. Now watchdogging static cvars.
] amx_cvar mp_timelimit 10
[AMXX] Cvar "mp_timelimit" cambiada a "10"
] amx_cvar mp_timelimit 0
[AMXX] Cvar "mp_timelimit" cambiada a "0"

This log message never gets printed, so the hook is not working

PHP Code:

#if defined USING_OKAPI
public OnCvar_DirectSet(const CvarHandle, const CvarValue[])
{
    log_amx("[STATIC] Something changed a cvar...") 


Okapi is running

Downloaded today a svends server and installed above. It works.
Can you please test with the same plugin?

Did you checked if plugin is running? Are you sure okapi is running? Use amxx modules and see.
