We have same Issue here, with current Chrome and Firefox browsers.

Klicking a mantis-link in my todo list, open in new tab, logs me immediately out of mantis.

Klicking a dokuwiki-link in my todo list, open in new tab, logs me immediately out of mantis.
Our Dokuwiki uses MantisBT Auth plugin. https://www.dokuwiki.org/plugin:authmantis

-- Environment
Using Mantis 2.26.0, nginx 1:1.24.0-1.el7, PHP 8.2, php-fpm 8.2.13-1.el7
Server logs do not show any error messages.

-- Findings
- after logging back in again, hitting refresh tab with the wiki page, logs me out again
- copy the wiki link into the address bar of browser doesn't log me out, works

Comparing a normal mantis page request with a request that logs me out
we find that MANTIS_STRING_COOKIE is/was deleted

Inspecting the wiki page while refreshing, shows a failing fetch.php in the 5.-10. browser request.
Cannot upload screenshot due to *Sorry, the board attachment quota has been reached.*
so i'll try to write it up:

1. doku.php?id=...
2. jquery.php?tseed=...
3. button-donate.gif
4. button-php.gif
5. button-html5.png
6. button-css.png

8. css.php?t=dokuwiki...
9. fetch.php=media=wiki:logo.png <<--- FAILED 403 Forbidden

Try if the mentioned workaround works for you https://www.mantisbt.org/bugs/view.php?id=33426#c68405

Yes, i can confirm the problem is solved with the following setting:
> As a workaround for this behavior, you can set $g_cookie_samesite = 'Lax'; in your config_inc.php.

Thank you for quick response

Me too.
I I click from an email to the link of mantis issue, there not able to login.
The error:
"Your browser either does not know how to handle cookies, or refuses to handle them."
If I just start from the browser, no such an error.
Windows 11 Firefox 121.0 (64-bit)
$g_cookie_samesite = 'Lax' in the config not helped.


What is the solution?

Did you also follow the mentioned step "Please note that users may need to log out and log back in, to switch the string cookie's secure attribute to the new value. "
