A string as an argument containing a valid format parameter (eg: "%s") will cause it to throw an error.

Changing log_msgf to:

/* Writes messages to log file depending on value of amx_ml_logmode */ 
log_msgf(const fmt[], {Float,Sql,Result,_}:...)
{      
    static buffer[512]
    vformat(buffer, 511, fmt, 2)
    
    replace(buffer,511,"%","%%") // stop %s from messing it up
    
    if (get_pcvar_num(g_cvarLogMode))
        log_to_file(LOGFILE_NAME, buffer)
    else
        log_amx(buffer)
}

fixes it
