OK, now we are getting somehwhere. I will show you what to do with the memberlist one and I'm sure it is similar for the others.
Here is the line in the code for the memberlist:
Code:
<td width="78" height="34" class="css_nav"><a href="memberlist.php$session[sessionurl_q]">$vbphrase[vb_members_list]</a></td>
See how it calls the phrase "vb_members_list"? You need to Search in Phrases for that variable (Languages & Phrases > Search in Phrases > enter phrase name in top box > check Phrase Variable Name Only and hit Find) The phrase will come up, hit Edit and change the name to whatever you want. Alternately, change that phrase to "$vbphrase[members_list]" which is the default vbulletin phrase and it should work.
Find each of the terms you are missing, search for the phrase and edit it and you should have it working.
