Unable to log out on the network

Can’t log out of ….? The main site? A sub-site? A mapped domain?

I can’t log out on any of my sites.
all my sites are in subfolders, but they all go to the same link and all give the 404 error

Delete all the cookies for your domain and try again.

If it still happens, turn off all plugins and test.

Tried both, does not work. Well kind of. I did go to the page not found page. But the admin bar wasn’t there anymore too. When I tried to go to wp-admin I got redirected to the 404 page again but his time with this url: https://<site>/wp-login.php?redirect_to=http%3A%2F%2F<SITE>%2Fwp-admin%2F&reauth=1

I hope you can help me

What plugins are you using? Anything to mess with logins?

Nothing I know that edits the login in any way.

Also without plugins it still doesn’t work! AND, i’ve found that commenting gives the same result. Another url of course, but the same page

What’s in your .htaccess?

Here it is:

RewriteEngine On
RewriteBase /
RewriteRule ^index\\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %\{REQUEST_FILENAME\} -f [OR]
RewriteCond %\{REQUEST_FILENAME\} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\\.php)$ $2 [L]
RewriteRule . index.php [L]

If those double back-slashes are for real, I think we have an idea. Try this:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

thanks you so much! That worked!
I don’t know why that dubble back-slash was there, pretty weird.
Anyway: Thank you!
