When writing or editing the text for a page, you may find that the text over runs the side of the “Edit Page” box and gets hidden behind the right sidebar, like this:

There are two major ways to address this issue:

The first, and simplest, is to use the “Full Screen” button to view the edit page area full-screen.  If you do this, your page will look like this.  You’ll notice that you only have access to some of your edit screen buttons, but you’ll be able to type your text in without any problems.

 

 

The second way to address this issue is to change your viewing setting to “One Column”

First, click “Screen Options” (in the upper right-hand corner of your Edit Page screen).

 

Then, choose “One Column” under “Screen Layout”

This will move the menus that were previously covering your text, and place them below the edit text box.  You’ll have to scroll down the page to use these functions, but you’ll be able to see all of your text.
