I would like to use all caps in the sidebar of description page, but the theme automatically changes the text to lowercase. Is there a work around?
Yes, it is possible. Please follow these instructions:
1. open page-description.php
2. go to line 37 containing this:
ucwords(strtolower($heading->plaintext))
3. Change following part:
ucwords(strtolower($heading->plaintext))
into
strtoupper($heading->plaintext)
NOTE: Please make sure that you changed correct number of round brackets (parentheses).
