find
Code:
<title><vb:if condition="$vboptions['cmstitle']">{vb:raw vboptions.cmstitle}<vb:else />{vb:raw vboptions.bbtitle}</vb:if> - {vb:raw html_title}</title>
replace with
Code:
<title><vb:if condition="$vboptions['cmstitle']">{vb:raw vboptions.bbtitle}<vb:else />{vb:raw vboptions.cmstitle}</vb:if> - {vb:raw html_title}</title>
but that only changes the order on articles!
you have to do that on all the templates you which to reverse the title on!
