Can you elaborate what you meant by “hide the sidebar”? Does it mean the side bar does not show up when you connect to my website? On both desktop and mobile, I do see the side bar shows up with ABOUT ME repeated twice (when not logged in) and eight times (when logged in). I can send you screenshots if it works better for you to investigate the issue.
I even switched the theme to others and came back to the Empathy theme, but it did not work.
Another piece of information: When I click the first ABOUT ME on the side menu, it links to different blog articles depending on web browser. On Safari, it links to the blog post #1, whereas Chrome redirects to the blog post #2. For both cases, though, it should point to About Me page, not blog posts. Hopefully, this info help you get a clue on this issue. Thanks!
Before bug report, I disabled all the plug-ins and confirmed the same issue persists. If you want me to disable all the plug-ins again, please let me know.
When you finish your investigation, could you please let me know? I’d like to keep it private until we know how to resolve the issue.
