Don't put any capacitor between the gate and source of the MOSFET.
You seem to have shorted VB and VS. Remove the short.
Put gate resistors between the IR2110 gate-drive-outputs and the MOSFET gates.
Put 1k resistors between gate and source of each MOSFET.
Remove the resistors and capacitors between the opto-coupler emitter and the gates.
For further information/ideas regarding the IR2110, refer to this:

Hope this helps.
