Hi, I am a web officer of a journal, using an OJS version of 126.96.36.199. As we are cleaning up our journal sections, we found that the section cannot be deleted unless all articles in that section is moved to other section. However, upon opening the “Submission and Publication Metadata” to change the section, we encountered a problem.
The metadata of that particular article won’t load, and upon inspection, we found an error saying:
Uncaught SyntaxError: Unexpected end of JSON input

[Deprecation] Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help, check https://xhr.spec.whatwg.org/.
I have searched the forum for similar issues, but to no avail. Any help will be much appreciated. Thank you very much
