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.
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.
