I have 8 categories in my gallery and 7 of them have replies to images.
It shows only for two of them.
"Last Post" column shows "Never" for 5 of my categories even though there are posts in each of them.
Check it here: http://www.goldenretrieverforum.com/gallery/
I tried to go to maintenance and re-count images and posts and replies, but it didn't help.
I have no idea how to fix it and if someone encountered something similar, please let me know how to get rid of this annoying problem.
