Hi Vlad59
I manually updated COPS on my Synology NAS to RC02, all seems to work properly.
I like very much the new Bootstrap template, but I think I found a bug in it.
In Calibre I use a Custom Serie column named "COLLANA", in COPS it is displayed properly.
But now if I enable Bootstrap template, entering in "COLLANA" I can see all the series contained in it, BUT the book count badge in the down right corner of each box is 0, it's only a display issue because if I enter in one of the series under "COLLANA" all the books are displayed as expected.
I hope my explanation is clear, english is not my primary language as you can see...
