i have vanilla 3.3 but lot of plugins does not works with it so how to downgrade it to vanilla 2.1
please help me
I take it you upgraded from 2.1? It is always recommended to take a backup before upgrading so that you can restore if things don't go as planned.
@Silentman: Which plugins you use are broken? Just out of interest, could you drop a list here?
Holy cow do not downgrade to Vanilla 2.1, it is riddled with known security flaws at this point.
