I have not made an entry in my site since the end of May. Still running 2.5.1, which had been working fine. The only plugin working is Akismet. Using a third-party theme (on this and other installs).
Today I logged in with Firefox 2 and found that most of the functions/buttons in Site Admin were missing. Beneath the title bar, the Write, Manage, Design, and Comments buttons do not appear; at the right side I see Profile where Settings, Plugins, and Users should be. Beneath that the white space is compressed and empty — no Posts, Pages, Links, etc. Then I see the alert for WordPress 2.6, and the rest of the screen appears to be normal.
Safari 3.1.2 works normally. I usually use Firefox for editing, however, because Safari has some issues with the WordPress editior.
What I have done to try to fix the problem:
- Quit and relaunched Firefox, and cleared the cache in Firefox (several times).
- Checked the server for permissions for wp-admin and wp-content directories; they and the active files within are set to 755.
- Checked .htaccess to see if there were any barriers; nothing there.
- Read all the posts on the forum during the past week or 10 days and searched further for similar reports. All I found related specifically to 2.6 and were no browser-specific.
The only other oddity is that I have a different username and password for that particular WordPress installation. The others (on different servers) use the one used for the support forum. Firefox works with the other; Safari accepts either for this site. Have no idea if that could be relevant.
Any advice? Thanks.
