Hey Chihte,
the jQuery code that truncates the text inside portfolio project boxes uses white spaces to separate words, so that the truncation points are always between words and now in the middle of words; please try adding white spaces to your text strings, this should help the mechanism display text in project items which do not have thumbnails.
Regarding your second question: I’ve added some custom code to your “content.php” theme file so that now the captions also show on projects which do not have thumbnails.
Sincerely,
Andrii / Satori Studio
