Error: With the new version of Bluespice and the new version of MW, we cannot add files or images to a page via the file uploader available in the toolbar. Also at Special:Upload the images or file does not render in the preview window upon upload.
Solution: Patch that solves this issue in "Upload image/file" dialog.
Error: InsertFile shows empty dialog
In BS free release its reported that InsertFile and InsertImage dialog are empty eventhough images/files exist in the wiki.
This is due to missing dependency in BSF/extension.json
Quick-fix for people with no tech knowledge is adding:
into MediaWiki:Common.js page
This will be fixed in next release.
