I Have encountered the error after the updation of the forum from SMF 1.1.11 to SMF 2.0 RC3 and then Installed the TP 1.0 Beta 5
In Tinyportal tab frontpage I selected the option "Forum-posts and articles - sorted on date"
Then I am getting the errors filled in error log

So I opened the TPortal.php from Sources folder and navigated to the articles
Quoteelseif(in_array($context['TPortal']['front_type'], array('forum_articles', 'forum_selected_articles')))
And added observed that all other if conditions defined avatar_height and avatar_width depending on some condtion but this one doesn't
So added the blank variables to the starting of the above quoted elseif condition. And this solved the problem.
Quote$avatar_height='';
$avatar_width='';
