Blogs lost all formatting after update

Hi. I updated our Joomla site today... from 3.10.10 to 3.10.11, and Easyblog to 6.0.10. All of my blogs and the image wall module have now lost all formatting, and some images don't display. I see someone else had the same problem. I cleared cache. Not sure where to start with this? The Stackideas Toolbar Package will also not update.

Thanks. Sarah.
