EDITING YOUR WEBSITE PAGES & POSTS
WordPress now uses BLOCK editing features — the video tutorials here below show you how to edit in BLOCKS. If you are more comfortable editing your pages/posts in “Classic Editor” mode, you can activate the CLASSIC EDITOR plugin to view and edit in the older method of editing.
Your HOME page may be created with WIDGETS. There is no longer a video for how to edit WIDGETS. Your widgets are found under the APPEARANCE link on your website’s dashboard. This is a youtube video that explains how to edit WIDGETs, CLICK ON THIS LINK.
