Thanks, I was under the impression that we are using a self-hosted version of ww.wp.xz.cn (5.7).
This is a screenshot of the Homepage of the admin area, https://drive.google.com/file/d/1ImmX-2BYQKUEuGsyM1lyb3OmsApSHrPY/view?usp=sharing
Are there any obvious ways to confirm that this is a wordpress.com site? I’ve inherited it and did not do the original setup.
