New Postbit
Old (Legacy) Postbit
While most people prefer the new layout of the postbit template after using it for a short time, there are others who are less willing to make the change.If you would like to run your board using the old-style postbit template, you can do so by going to vBulletin Options > Style & Language Settings and switching the Use Legacy (Vertical) Postbit Template? setting to Yes.After clicking the button, all your styles will use the Legacy (old style) Postbit.
Note:
If your board is set to use the Legacy Postbit template you should be aware that you will need to make any postbit-related template customizations to the postbit_legacy template instead of the postbit template.
