When Debug Bar Console plugin is active, the File Browser popup window shows a blank page, instead of the list of posts and pages.
I'm not sure about the reason of this conflict, but I think you would like to know it. Anyway, after deactivating this plugin, everything works OK in WP-Filebase.
WP-Filebase is a great plugin. However, when working in the spanish translation, I've noticed that some text chains are not ready to be translated. If you are interested, I can send to you my translation and the list of these text chains.
