 Okay, I just upgraded my site to WordPress 5.0.2

 I tried to edit an existing post, when I converted the contnt to block
 editor, the auto save kept telling me update did not happen "Updating
 failed", when I tried a preview, it never showed just keeps drawing he
 WordPress logo and "Generating preview…"


 I installed and activated the "classic editor" plugin and tried to edit
 the edit box is totally blank!

 I went back and deactivated the classic plugin then went to the post to
 edit but it was totally blank except for the header box and bellow a faint
 box with the title of "Classic"

 Fortunately I found an option "Convert to Blocks" when i did that, the
 content re-appeared but the "preview still does not genrate.

 My current theme is Twenty Seventeen Version: 1.9

 I  went back to the post to try to recover a previous version, but there
 is no revisions history and found no option to activate.

 I searched the forum for help on reviosions and found * * adding line to
 save post revisions  per WordPress
 {{{
  */ https://codex.wordpress.org/Revisions
  */ and at https://codex.wordpress.org/Editing_wp-
 config.php#Post_Revisions
  */
 }}}

 I have edited wp-config  with these lines, I am guessing I have o log out
 close the browser and revisit the site for that code change to activate. I
 have no idea what to do from there.
