How to read blank email?

How come I can send and read my message prior to sending but the message screen on email received is blank?

• Text messages of my email directory went blank. No messages appear on each email record. I emailed you early this morning and you replied but no messages ..all blank too.

  In the new Yahoo! Mail, you don’t do this with your browser anymore. Now, just change your character encoding setting right in Yahoo! Mail! Here’s how: In the toolbar, click More Actions and select Set Encodings. From the list that appears, select the encoding that matches the message’s content. Note: Only one character encoding set may be viewed at a time. And in this case, changing your browser’s encoding setting will not work. Or in the old Traditional = Select any email where the header information is displayed, but there is nothing in the "body" of the message where you would expect to find text, etc. Move your mouse to the area of the expected "body" of the message and right-click...on the menu that appears, click on "Encoding"...on the menu that appears, if "Auto Select" has a check mark, leave it as is...if not click "Auto Select"; then this menu will disappear...right click again in the "body" to cause the same menu to display again...then click on "Western European (Windows)"...you should now be able to view the "body" of all messages that you couldn't view before...obviously, if the problem somehow occurs again, do the same procedure described above again. I have no idea how or why these settings get "changed" or "corrupted" after everyday use, but apparently they sometimes do.
