Hi #Jeremi,
Thanks for your help, but, if I logout from wordpress.com, all the modules are disabled, aren't they? As far as I know, to logout from wp.com is just like disabling Jetpack, right? Because when I do it all modules stop working :(
About the traceroute, the hosting server is in Iceland, but I'm in Norway. The traceroute will be done from Norway, not from Iceland. Is it useful?
about the PHP settings, memory_limit is 256MB and max_execution_time is 30s. Isn't it enough?
