index.php file in the plugins folder makes the Dashboard fail

[networker]

The "Dashboard" tab in WordPress 2.5 at the far upper left contains the following URL:
​http://www.example.com/wp-admin/admin.php?page=index.php

When this tab is clicked it, all the Dashboard widgets disappear in Firefox (2.0.0.12). I'm left with a plain screen of links.

When the page is pulled up with the following URL: it works fine with all the Dashboard widget functionality.
​http://www.example.com/wp-admin/

My dashboard link using r7579 points to /wp-admin/index.php.

When I try going to the link you gave, I get "Cannot load index.php." in Opera 9.26, Firefox 2.0.0.13 and 2.0.0.12. IE7 gives me its generic "Cannot be displyed" error page

Works for me on FF & IE 7 using r7583

Works for me as well.

Disable all plugins and try again.

I'm still getting the issue with today's 2.5 branch. no plugins, default theme.

Milestone 2.5.2 deleted

Re-open if still current in 2.7 and not a local config issue.

I nailed this down since. It was due to the presence of an index.php file in the plugins folder, and the bug is, I suspect, the same as this one:

​http://trac.wordpress.org/ticket/6422

still current in wp 2.7 with an index.php file in the plugins folder

Its quite easy to "fix" this, Simply removing all references to file_exists() in wp-admin/menu-header.php will work.

However, Doing so, Will remove the ability for plugins to have menu items which are linked to files which are dumped into the wp-admin folder (There are a number of cobbled together items where people have been directed to put files in wp-content AND wp-admin), It'll also remove the ability for overriding admin pages via a .php file, It'd still be possible to hook via a action tho.
It might also remove the menu for any old plugins which add their menu item manually via array-fu

The menu code seems to need a clean up to me, I'd love to be able to specify the exact URL for a menu item when adding (ie. wp-admin/posts.php/test/example or post.php?example=url), as well as a few other items.. But staying backwards compatible is hard.

Setting to 2.9 due to no patch. Can be pulled into 2.8 if/when theres a patch, Unless its decided to leave it as-is to retain functionality. dev-feedback to see if menu should be changed, or existing functionality retained.

actually fix this and optimize

applied patches don't work. attached patch fixes the issue, and places the check before the calls to file_exists to avoid uneeded filesystem calls.
