I used Firebug (http://getfirebug.com/) in FireFox 3.0 to "Inspect" the unresponsive All In One SEO postbox control on the WordPress Edit Post page. This helped me locate the postbox code in the SEO php code.
The workaround is to:
1. Deactivate the All In One SEO Pack plugin.
2. Edit the SEO plugin code from the WordPress plugin
management page.
3. Remove the 'closed' option on the postbox class.
Change the original code from class="postbox closed":
<?php if (substr($this->wp_version, 0, 3) >= '2.5') { ?>
<div id="postaiosp" class="postbox closed">
to just class="postbox" as shown below:
<?php if (substr($this->wp_version, 0, 3) >= '2.5') { ?>
<div id="postaiosp" class="postbox">
This defaults the SEO postbox display in expanded mode showing the various input controls. I think the default display mode should be expanded instead of hidden anyway.
4. Reactivate the SEO plugin.
I verified the fix works by inputting the SEO options for a new post and viewing the HTML source from the web browser, which contains the following HTML entries:
<!-- all in one seo pack 1.4.6.15 [211,308] -->
<meta name="description" content="Water dripping from the ceiling was traced to leak from the upstairs shower/bathtub. Steps for finding and fixing the leak are explained with photos." />
<meta name="keywords" content="access panel, bathtub drain, ceiling leak, drop ear elbow, drywall, finding a shower leak, how to, inspection and repair, leaky bathtub, maintenance panel, pipe joint compound, plumbing, rotozip, shower head, shower valve, teflon tape, water stain, wet wall,bathtub drain,ceiling,drop ear elbow,drywall,finding a shower leak,how to,inspection and repair,leaky bathtub,maintenance panel,pipe joint compound,plumbing,rotozip,shower head,shower valve,teflon tape,water stain,wet wall" />
<!-- /all in one seo pack -->
Why the above HTML comment says version 1.4.6.15 I'm not sure as All In One SEO Pack shows ver 1.4.6.16 on the WordPress "Manage Plugins" page.
I verified the SEO form data I entered is retained for the newly updated post and as well as my older posts.
