This OJS 3.1.1-2 install was migrated from 2.3.3.2 to 2.4.8.3, if that’s relevant. The reviewer files > more information > history just hangs at spinning progress wheel indefinitely. Log doesn’t help much:
xxx.xxx.xxx.xx - - [31/Aug/2018:11:08:41 -0400] "GET /index.php/URL/$$$call$$$/information-center/file-information-center/view-history?submissionId=550&fileId=3283&stageId=3&_=1535726668617 HTTP/1.1" 200 631
I’m not even sure there is data to display, but I wouldn’t think it would hang at the spinning progress wheel even if that were the case. Other reviewer files > more information produce the same result.
