Won’t preview a post draft, or published post

Dang, that gives a 500 error.

If I alter

RewriteCond %{REQUEST_URI} !^/wp-(admin|json)/

to

RewriteCond %{REQUEST_URI} !^/wp-admin)/

or

RewriteCond %{REQUEST_URI} !^/wp-json)/

No error, and with wp-json excluded Gutenburg works ??

Ahhh, you could split it up then, as you can add as many conditions as you’d like. I guess my pattern isn’t supported, so apologies for that ??

for me i have probably the same problem.. but..
when i press preview button, nothing happened.
opened new tab about:blank
and.. generating preview.
and thats all

but! if i press right button to preview button and click open it in new windows it works

pls help!

OK.. found.
i deactivate gutenberg in plugins, and it almost works (may be it was some conflicts between builtin gutengerg and plugin)
why ALMOST
when i push preview button, it generates preview in new window, but it opens an already saved copy of my post, not changed one. but if i press refresh button, it shows me the right one.

why so?

Hi @obsidianurbex and @clorith

This was VERY helpful! As it turns out, this is something of an obscure issue and there was not much online to solve this.

I had the EXACT same issue with the .htaccess code forcing the trailing slash. I had even put out my own ticket for it looking for answers, but then came across your post.

The only problem I’m having is that when I use the modified .htaccess code, the problem repeats itself. The ONLY way I’m able to publish or modify posts is by deleting the code from .htaccess.

Did you find a code that worked for the trailing slash and also allowed you to publish and update posts?

Edit:
I was able to find this code which worked just fine and allowed me to force the trailing slashes and still be able to post

# Force trailing slash
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_METHOD} GET
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteCond %{REQUEST_FILENAME} !\.(gif|jpg|png|jpeg|css|xml|txt|js|php|scss|webp|mp3|avi|wav|mp4|mov)$ [NC]
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1/ [L,R=301]

I found it here: https://docs.wp-rocket.me/article/131-redirection-to-enforce-trailing-slash-on-urls

Cheers
