Over the summer, library staff have encountered some issues accessing electronic resources and discovered that the block is caused by the Zotero Connector browser add-on in both Chrome and Firefox.
If you already have the Zotero Connector installed, we recommend uninstalling and reinstalling it in all the browsers you use. (In our testing, we have found that first-time installations of the add-on seem to be unaffected.)
Visit our Zotero guide for quick access to the download link.
