This week, the display of albums broke on my staging site, and the only thing I can conclude is that it was related to some plugin updates (only using the default ones that come with the theme). For example, on my home page (which is a simple slider album display) - the album and the header do not display anymore. When inspecting the page source, I was able to find this error, and am hoping you might be able to help me figure out the cause:
: Uncaught Error: Call to undefined function apollo13framework_make_slider() in /homepages/8/d718619715/htdocs/app719496042/wp-content/themes/fatmoon/single-album.php:158

Have you overwrite some templates or function in child theme?
If yes, then I would suggest disable child theme, and then reimplement changes, as there where some code rewrites in 1.6.x to introduce new shortcodes.
With kind regards.
