On a WordPress site, earlier, I could see the preview of math equations (written in the body of a question section, not in the Title. Just like this SE website has question Title and Body sections, where in Title you write short description and in the body you describe the question in detail) on the mobile version of the site beautifully. Suddenly I don’t see the preview of math equations in the body of question but only see the question and some math in the Title. I do see the entire math equations when I click the question and go inside. I think it happened after I installed W3 Total Cache (which also rendered the mobile version bit differently than what it should be). Now I deactivated, then deleted that plugin but the problem is still there. I deleted minify directory and cache directory even from my public_html directory in the server and checked .htaccess. I don’t see any W3TC entry in .htaccess file. What maybe the problem and how to restore old glory i.e., to see the preview of the questions with math equations without clicking the question.
