When i open this link on other language i view just loading infinitely also i can’t rewrite this “Submission Preparation Checklist” on English. I get error “Failed Ajax request or invalid JSON returned”. My OJS Current version: 188.8.131.52 (March 16, 2021 - 02:15 PM)
Sorry guys i found solution: [OJS 184.108.40.206] Failed Ajax request or invalid JSON returned in Workflow Settings - #7 by Enrique
display_errors PHP setting to OFF in file config.inc.php and now it’s working as expected.
