issue2: You can send me your site for further checking.

If you want to hide the social share section in the DW Q&A page, you can add the following code to the style.css file:

/* Single question page */
.single-dwqa-question .us_posts_top {display: none; }
.single-dwqa-question .shareaholic-canvas {display: none; }

– To resolve the issue with the dropdown (Public,..) section, please deactivate  all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one and let us know if you find the problematic plugin(s). Maybe there is a conflict in plugins.
