New version, old problems
Just updated my Zotero to its newest version and all my connectors crushed. I tried reinstalling connectors for Chrome and Safari, nothing works. All extensions are just there but not doing anything. It does not even show up when using Safari. How can I degrade to its previous version. I do not have time to solve all these issues and would just prefer to calmly use my previous version.
Upgrade Storage
For Chrome, see Troubleshooting Problems Saving to Zotero. There were no Connector-related changes in Zotero 9.
