I believe I have the same issue as the OP. My site does not use bootstrap. However, the Bibbase script is applying a stylesheet located at that is styling @media (min-width: 1200px) .container with a fixed width of 1170px. Unfortunately, .container is a very common class name so this creates problems, in my case a narrowing of the width of the entire page, not just the publications list. I was able to work around the issue by adding the inline style="width: inherit" to my <div class="container"> tag in order to take precedence. I hope this helps others facing similar problems. The issue did not appear to be able to be overcome either by selecting a different theme (such as "simple") or by specifying a custom css style file.
