Fixed security problems. Go to both templates, find the forms and add this code somewhere in them:
Code:
<input type="hidden" name="securitytoken" value="$bbuserinfo[securitytoken]" />
Then I followed some advice meant for vB Shout and changed this in vBulletin global script:
Code:
datastream + "securitytoken="
To
Code:
datastream + "&securitytoken="
It then all worked.
