Please help us by providing the following info. Before posting please also check the pinned "Known issues" threads and make sure that you're running the latest available version for your oC release: https://owncloud.org/changelog/
Steps to reproduce
1. Click the "Add to ownCloud postlet on my browser.
2. Type keywords in popup window (optional).
3. Click "Save."
The bookmark should save and the window closed as it has in the past week (the last time on February 20).
Nothing happens; the save button doesn't work. The window stays open. I close it and the lose the data. If I go try to add the bookmark directly to the app, I get a message that says "Could not add bookmark."
