Sidebar move in down the post

Hi,

I don’t quite understand what you mean. If you have a problem, please provide a link to your website we will inspect it.

Usually layout issues are caused by modifications to the theme, custom code or maybe having both composers active at the same time.
Try deactivating all plugins except theme plugins, leave only the composer you are using active (either Visual composer or tagDiv composer) and other theme plugins. Temporarily remove any custom code used in the theme panel, or code entered in theme files.
If you use a child theme switch to the main theme. Try these suggestions and see if you can identify what is causing the issues.

Thanks
