Thank you for reporting the problem. I found a bug with the taxonomy query and fixed it. I just updated the plugin to version 1.0.1. The update should appear on ww.wp.xz.cn shortly. Sorry for the inconvenience.
Thank you for trying out combine-galleries. The shortcode has a “debug” option that will display the output text of the shortcode. Do you mind trying the following and letting me know what you see?
[combine-galleries category=”galleries” debug=”true”]
Meanwhile, I will set up a test site that we both can access and I will try to reproduce the problem. Give me an hour or so to investigate.
Regards,
John
