Cannot import styles
I am unable to import any styles into Zotero. I get a security certificate error. If I download it from the database and try to add it, I get an unexpected error. The ID is 1673756044. Thanks for any info on how to solve this.
Also, what exactly is the error you're getting when adding the style manually and which style are you adding?
It doesn't sound like you actually tried all the steps (since one of them is "talk to your IT department, and depending on what they say follow these certificate-override instructions"), but instead of doing that I'd suggest trying the Zotero 7 beta, which, as noted on the cert-override page, should automatically use a custom system root certificate on macOS, which may very well fix Zotero's ability to connect to the internet on your network.
