I decided to copy and paste my problem above into a support ticket for our webhosting company. They said that the WordPress upgrade to 4.7.5 somehow changed the permissions for those 3 files. Therefore they couldn’t be found. The support guy changed the permissions and suddenly I could access all 3 files in the WordPress backend like normal. Hurray!

OK good idea. These 3 give me the 404 error.

I looked and all 3 files are present in the wp-admin directory. It’s very puzzling.

I’m running WordPress 4.7.4 on a mature site that’s 3 years old. Since this latest update, I’m having 404 problems with these…

Click Appearance > Customize = 404 error
Click Appearance > Widgets = 404 error
Click Appearance > Menus = 404 error

When I Click Appearance > Themes or Editor = works normally

These were all working normally before updating to WP 4.7.4. Has anybody seen this or know of a solution?

Thanks for posting your link above. I did all of the things that Bob suggested and I still had no editor.

However, I looked at my error log in cPanel and it said that post.php had it’s permissions set to 664. I changed it to 644 and I suddenly have an editor to use! Hurray! I can now do my job!

Yes, wp-config.php is the default. The # Custom Settings was already there. I just copied it with the line that’s supposed to solve this 404 problem beneath it.

The missing URL is the editor for every page and for every post. If I click edit, the Editor is replaced with a 404 page. I jumped in here with the same problem as Will who started this. He wrote…

“Since I upgraded to 4.2.3, I am no longer able to publish any content on my website, as the visual editor is no longer working. I am unable to even add content as html. Neither the visual nor text tabs are working for posts or pages.”

I tried editing wp-config.php by adding it like this:

# Custom Settings

define(‘SCRIPT_DEBUG’, true);

The 404 error remains for the page and post editor.

You wrote:
2. Find the line:
/* That’s all, stop editing! Happy blogging. */

My wp-config.php file doesn’t have that line.

Ditto for me too. I did the auto update to 4.2.3 on 5 sites. 4 work just fine but the 5th is giving me 404 errors for the post editor and the page editor.

I tried to roll back my site to 4.2.2 manually by copying everything from a 4.2.2 zip file by FTP. The 404 errors for both editors remained, so I did another update to 4.2.3. The 404 errors remain for the editors.

I read on here to change the Permalinks and then put them back. The 404 errors remain.

I read on here to change the .htaccess file, but there was no word on what to change it to. I deleted it and I got a 500 Internal Server error. I took the .htaccess file from a site that’s working and the 404 error remains for both editors.

Does anyone have any ideas on how to get the editor back?
