Works of other authors are not displayed

I am not sure at what point in time, but the button to view the author's work does not appear and I cannot view it. This is also the case with my personal page. In addition, the folders in my favorites that I had categorized in the past have disappeared, and the favorites in those folders have disappeared as well. Please put them back as soon as possible.

The system of this HP has been deteriorating badly lately.

　It seems to be getting worse with each modification.

　Are you aware of this?
