Hi @asmecher
I can confirm that I’m seeing the same error described here by @cridum (stuck on Loading when I click on Editorial History) on my OJS v3.1.2 installation. The Fix editorial history for emails with sender_id=0 · Issue #4655 · pkp/pkp-lib · GitHub patch you mentioned above does not seem to resolve it.
As mentioned by @Zetsaika in DB: Unknow column 'Array' - OJS 2.4.8-2 to 3.0.2 Upgrade - #16 by Zetsaika, I’m not seeing any errors in my PHP error log either.
Any suggestions would be welcome.
Regards
Reagan
