Just found out this:
In template FORUMDISPLAY you use this code:
HTML Code:
<div class="titlebg">{vb:raw foruminfo.title_clean}<vb:if condition="$show['newthreadlink']">
<a id="btn" style="font-weight:normal;font-size: .8em; border: 1px solid #999999;color: #000000;" href="newthread.php?{vb:raw session.sessionurl}do=newthread&f={vb:raw foruminfo.forumid}" rel="nofollow">{vb:rawphrase new} {vb:rawphrase thread}</a></vb:if>
Use instead phrase {vb:rawphrase post_new_thread}
So that there is this code:
HTML Code:
<div class="titlebg">{vb:raw foruminfo.title_clean}<vb:if condition="$show['newthreadlink']">
<a id="btn" style="font-weight:normal;font-size: .8em; border: 1px solid #999999;color: #000000;" href="newthread.php?{vb:raw session.sessionurl}do=newthread&f={vb:raw foruminfo.forumid}" rel="nofollow">{vb:rawphrase post_new_thread}</a></vb:if>
Problem is that my language (Croatian) is a bit more complicated than English and I know that this is similar with Spanish, German and many more of them. It is correct phrase for this button and it's much better to use it instead two phrases.
