Whoops, didn’t know commercial themes weren’t supported by this forum. I will try the tips in this thread, and if they don’t work, I’ll contact the theme’s developer. Thank you, all three of you!
Edit: For anyone who reads this thread with the same problem, Amado.Miami’s solution works. You have to enter it into each caption, however, so it might not be the best long-term solution for some. It will make your captions visible until you can figure out how to change your theme, and I believe it will work in any theme.
