I'm hearing from different people that they have compile issues with latest reapi release. I don't faced this issue but I've tested on local with latest rehlds, regamedll and reapi and especially one plugin with RH_ExecuteServerStringCmd hook:

#include <amxmodx>
#include <reapi>
 
public plugin_init()
{
	RegisterHookChain(RH_ExecuteServerStringCmd, "ExecuteServerString")
}
 
public ExecuteServerString(cmd[], source, id)
{
	server_print("%s", cmd)
	//server_print("command: %s | %d | %d | %n", cmd, source, id, id)
	if (equali(cmd, "status"))
	{
		console_print(id, "Unknown command: %s", cmd)
		return HC_SUPERCEDE
	}
	return HC_CONTINUE
}

Output from server_print("%s", cmd): major version mismatch; expected %d, real %d

And the blocking behavior does not working.

The server console is clear on startup.
