You are right, signatures have nothing to do with this. I have just upgraded from 1.5.x and been working on my forum for xx hours now and am a bit tired.
Code for displaying info on my forum on mobiles is:
display: block !important;
I need to move my 500k+ posts forum to new server and just wondering whether it could run on good shared hosting or VPS only?
I have about 400-500 users online at the time.
What do you think is most that shared hosting could run?
