Origami template not showing date correctly

I have installed the template Purity III from Joomlart. The origami template is my favorite one but is not showing the date below the avatar correctly. The number appears within 2 rows and the text of the month brakes also into 2 rows. This doesn't look very nice. I found some hints in this forum and I downloaded the recommended blog.meta.php but it did not work for me.
Can you please make a suggestion how to fix this issue? Thanks a lot.
