Logged in a few minutes ago to find there’s a new WP version already. I have an issue, though~ This comes up whenever I click on the “Add Image” in the “Add media” bar.

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘media_admin_css’ was given in /****/****/public_html/****/wp-includes/plugin.php on line 311

ALSO, If you click on this post WP shows me a 404 ERROR. What’s happening!! Permalinks that include index.php are not working, so Categories are not working, Pages are not working, Archives is not working. Will stop blogging, until issue is fix.

*EDIT*
De-activated Flexible Upload, and the WARNING Message in the Add Image went away. Still got the 404 Error with the permalinks, though~ Le sigh.

**EDIT**
Successfully downgraded to WordPress 2.5.1

***EDIT*** 3.36am
Successfully edited permalinks without index.php, will try WP 2.6 later. Off to bed.

****EDIT**** 3.03pm
Ok, that worked. AM now using WP 2.6, but as u can see all links don’t have the index.php thing. LOL’ Good WP move so people have to make the switch to ‘pretty’ permalinks. Hee. Ok, not so funny. It was pretty annoying… this is what you need to do to change it…

Get your .htaccess file, and add this:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

Then go to your WP admin, go to Settings, Permalinks and do your thing.
/year%/%monthnum%/%day%/%postname%/

After that, WP 2.6 is all dandy. Otherwise, go to the WP Forums coz they’ve got another option.
