I posted this issue on another thread then found out I should have started a new one so here it is.
I just transferred my blog http://juliedawnfox.com/ from WP.com to WP.org
I had problems importing the XML file and had to manually attach most of the photos in the media library to posts (over 700!).
I quickly became a huge fan of the rectangular and circular galleries at WP.com and have several posts that make use of them.
Unfortunately, they don't work now that I'm on .org - all I can get is the basic gallery of thumbnails with the caption underneath which looks messy. The carousel doesn't work, either.
I'm using the same theme, Oxygen by Galin Simeonov, as I was before.
I've tried cancelling galleries and creating new ones within posts but all I get is the above mentioned thumbnails.
For example, here's a before and after of the same post.
What can I do to resolve the issue?
By the way, I know nothing about HTML.
