But vB4 offers us the option "Use Legacy (Vertical) Postbit Template":
If you prefer the old-style postbit, using two vertical columns rather than the new horizontal layout, you can switch back to using that template with this switch.
Please note that if you enable this option and wish to customize the template, you should edit the 'postbit_legacy' template rather than the 'postbit'.
I have enabled this, so my forum is using the postbit_legacy template.
In photopost i have enabled the option: "Do you want to enable the vB3 or vB4 Integration which uses your vB3 or vB4 headers, footers and styles?"
So with this option photopost should use the vB4 styles that I've setup up. In this case the legacy style.
Since photopost is sold with a working vB4 integration, I think not using the postbit_legacy setting is a bug or shortcoming. As you said yourself: photopost with vb3 integration and enabling the vb3 styles, the column for avatar is used.
So it seems like photopost is ignoring this vbulletin setting and just show the new postbit template. Can you fix this bug?
