For anyone else with the parse error…
The problem files are:
/libs/socialconnect/facebookconnect.php
/libs/socialconnect/linkedinconnect.php
/libs/socialconnect/twitterconnect.php
#1 Make a backup of those 3 files for posterity 😉
#2 If you don’t need them (which i don’t) then edit and delete everything after the <?php
Now you can at least install the update and the download manager works as intended.
Maybe the site-owner can get eventually get around to fixing those 3 files… but judging by the posts in this thread i won’t be waiting
on an update with baited breath :p
