* This might be the same problem as experienced in this post:

* Its not solved yet. Somehow after the classic editor got moved out of core in
some cases its not (re)directing to the correct file/location anymore on saving.
* Could this be an improper redirect to mysql or from wp-includes folder to wp-
admin? I do not see a solution but maybe somebody does.

* Found that the error only occurs on posts created before install 5.0 and Classic
Editor also some pages fail some don’t and If I am editing a page I can not add
media Click insert into Page and nothing happens Why did WP fix something that
wasn’t broken almost all my sites use custom html and javascript. If I even open
them with the Gutenberg they break. Anyone ever downgrade a WP Version?

* Ok so I picked a site deactivated all plugins except Classic Editor If I try
to edit a post “Update” or preview changes I get Page Not Found with a URL
* [https://mydomain/wp-admin/post.php](https://mydomain/wp-admin/post.php)
* It is missing ?post=29&action=edit
* This happens on 4 out of 7 posts on this site there are only 7 posts.
* I have pinned it down that this happens to any post with an image in it also
the image will not show up in the visual editor. The code in the post that breaks
the plug in is like this
* `

* I can bulk update posts what i tried was changingg author on all posts and then
changed back.
* I also noticed that

* Its good that you disabled all other plugins when testing. So if all plugins
are disabled including the Classic Editor plugin you have no problems saving
posts?, then when you enable the Classic Editor plugin (leaving all others disabled)
you start to have problems saving drafts/posts?
* Only thing that i can think of to experiment is to see if the problem also occurs
with older versions of the Classic editor plugin, you can find and download older
versions on the bottom of this page: [https://wordpress.org/plugins/classic-editor/advanced/](https://wordpress.org/plugins/classic-editor/advanced/)
* I do most on my server via ftp like updating plugins and updating WordPress.
Via FTP you can easily remove a plugin and replace it with an older version.
* Maybe that can help pinpoint if things go wrong from a specific version.
* Other thing you could look at is at the permalink settings of your website via
_wp-admin > settings > permalinks_. Maybe something is mixed up there, the correct
piece of code to be included in the .htaccess file that then should be placed/
is located in the same folder as the root files of WordPress should be shown
at the bottom of the _wp-admin > settings > permalinks_ page.
* Also good to check if you might have other custom .htaccess files or custom rules
in a themes functions.php that might interfere.
* Downgrading your WordPress to 4.9 could i think be an option if you have a database
backup from before the upgrade to WP 5, then you would be sure that you could
undo any changes that might have been made on WP 5 becoming active. I do all
my database backups and restores via phpMyAdmin.
* I myself made the choice to stay put on the most recent version of WP 4.9 ([https://wordpress.org/download/releases/](https://wordpress.org/download/releases/))
for the time being and use Classic Editor 0.5.

* From what I can see this is an incompatibility issue with WordPress 5.0+
* I disabled all plugins except Classic Editor, enable debug logs and tested some
older versions of the plugin.
Versions of Classic editor <0.5 will work with
WP 5.0 but do not give the same user experience. With Classic Editor 0.5+ I get
the following log messages:
* ```
PHP Notice: edit_form_after_title is deprecated since version 5.0.0! Use block_editor_meta_box_hidden_fields instead. This action is still supported in the classic editor, but is deprecated in the block editor.
PHP Notice: edit_form_advanced is deprecated since version 5.0.0! Use block_editor_meta_box_hidden_fields instead. This action is still supported in the classic editor, but is deprecated in the block editor.
```
* I’ve not attempted to fix the PHP code as yet.

* Everything so far is pointing to breaking changes with the WP5.0+ new block editor.
I’ve experienced similar issues with a number of plugins now and have reverted
WP back to v.4.9.8.
I guess we’ll have to wait a while to see what the resolution
to these issues are, whether this will be a change in WP core or all plugin authors
will have to work around these issues. I’ll be sticking on v.4.9.8 for some time
to come I’d imagine.

* [@djparker](https://wordpress.org/support/users/djparker/) thanks for your input,
maybe it helps the plugin author to find what could be going wrong. It at least
shows that your problem starts occurring in combination with the 0.5+ versions
of the plugin but as only so few people seem to have this specific issue it is
not a issue between only Classic Editor and WP 5 otherwise 1.000.000+ people
would have the problem so its a more complicated to pinpoint combination of things
in some peoples setups.
* What your PHP deprecated notices sadly do show is how fast the WP 4.9 and WP
5.0 worlds are drifting apart :_–_(
* BTW as you reverted to WP 4.9.8 you could also update to WP 4.9.9:
[https://wordpress.org/download/releases/](https://wordpress.org/download/releases/)
* It has a couple of recent security fixes:
[https://codex.wordpress.org/Version_4.9.9](https://codex.wordpress.org/Version_4.9.9)
* I updated to it myself manually via FTP, updating via the dashboard probably
only ends up in getting WP 5. If someone also wants to do a manual upgrade then
be careful!!!, backup and not everything should be deleted/overwritten: [https://codex.wordpress.org/Upgrading_WordPress](https://codex.wordpress.org/Upgrading_WordPress)

* BTW for anybody having this problem: switching themes might also be something
to try, to exclude there being problem with that.

* As @damsko pointed out above, there is _something_ that is trying to use the `
edit_form_after_title` and `edit_form_advanced`filters when it shouldn’t. As
all plugins are disabled, the culprit is probably the theme, or some sort of “
hack” you may have added some time ago and forgot about. Another possibility
is a “helper” plugin in the`mu-plugins` directory. Finally, your production site
should be set to hide PHP notices, unless you also use it for testing 🙂

* It might be an option for some to look if the “Disable Gutenberg” plugin could
do the job for them without the conflicts that they are now experiencing when
using the Classic Editor plugin. The Disable Gutenberg plugin has the same functionality
and that is to disable the block editor and restore the classic editor:
