Describe the issue or problem
Please tell us what happens and what you expected to happen.
A new manuscript was submitted to a multijournal (currently 2 journals) OJS site. This is a clean installation. When the editor (or the system administrator, or journal manager) tries to display the new submission by clicking the View button, a modal window pops up and Error Call to a member function getData() on null message is displayed. The editor can’t see the details of the submission. The reviewer suggestion option is enabled in Workflow settings. Other submissions can be viewed and processed succesfully.
Steps I took leading up to the issue
For example:
- Go to Active submissions
- Click on View button of the new submisson
- The modal window pops up and Error Call to a member function getData() on null
What application are you using?
For example, OJS 3.5.0-1
Additional information
Please add any screenshots, logs or other information we can use to investigate this problem.
