Hi,

Here is a screen cast of the issue: http://screencast.com/t/ZquL9DBgvxmU

A Magento 1.4 site I administer was ported from Plesk+Apache to cPanel+Nginx recently, and all seemed fine, except, the Catalog > Manage Categories page has a lot of categories. The issue persists through both the latest stable Firefox and the Google Chrome browsers.

Once the categories are made, editing them on the web interface seems impossible. AJAX [i]seems[/i] to run fine, since I get the "Please wait" icon, but if I click a category, I cannot edit it because it doesn't load from the left pane onto the editing pane(s).

This thread on Magento's site details the same issue: http://www.magentocommerce.com/boards/viewthread/200317/#t254131

Magento config:

[code]
location / {
index index.php;
try_files $uri $uri/ /index.php?q=$uri&$args;
}
location /skin/m/ {
rewrite ^/skin/m/([0-9]+)(/.*\.(js|css))$ /lib/minify/m.php?f=$2&d=$1 last;
}
[/code]

Note sure that skins part is necessary; saw it on another site and used it. I'm running Nginx 0.8.53, also have and open_basedir and APC entry in the PHP section, and fastcgi_pass is using PHP 5.2.14 running through spawn-fcgi.
