PLUGIN IS ACTIVE: Yes
PRESS SAVE.
Now just add $terms in any template you want.
+++ IF YOU'RE USING Ted S - Improved Welcome headers from vbulletin.org +++
Styles & Templates -> Style Manager -> welcome_headers
FIND THIS:
CODE
<phrase 1="faq.php?$session[sessionurl]" 2="register.php?$session[sessionurl]" 3="$vboptions[bbtitle]" 4="sendmessage.php$session[sessionurl]">$vbphrase[welcome_guest]</phrase>
REPLACE WITH:
CODE
<phrase 1="faq.php?$session[sessionurl]" 2="register.php?$session[sessionurl]" 3="$vboptions[bbtitle]" 4="sendmessage.php$session[sessionurl]" 5="$terms">$vbphrase[welcome_guest]</phrase>
SAVE!
NOTE: The difference in the code is adding: 5="$terms" to the phrases. This will allow the $terms variable to work with the welcome headers for guest.
It's just an issue with the regular expression the guy who wrote it originally is using.
