I posted a question yesterday, Output characters to Word document with different formatting for each character. When I tried to edit it I was told that Stack Overflow was in read-only mode. It is still saying that today.
There are two links at the top, one to the status page and one to recent meta posts on the topic. Neither of them says that there is any problem.
There have been multiple reports in the comments and on other meta sites that this problem keeps happening to various users ever since the initial report (and likely there have been more incidents that were not reported at all), hence the close reason that it “can no longer be reproduced” is invalid.
