Zotero local will not start up
Zotero on my MacBook Pro w/ OSX 10.14.6 will no longer start up, instead endlessly showing the start-up bar. I let it try for 24 hours, nothing, so have to force quit. I am successfully using my Online Zotero library, and that seems intact. What can I do to get Z to startup on my local machine? I tried deleting my prefs and User Profile but that would not work ... any advice on problematic start-up solutions would be nice!
