Hi, Alphawolf.
WP 2.9.2, Firefox Mac 3.6.3
I set page title, slug etc., clicking Save for each, and the settings look like they've taken. All looks good, no indication of anything abnormal.
As soon as I navigate away, refresh the page, or check the regular WP fields for any of those settings (all after saving), either at the time, or later, they've gone. With testing further to my initial post, I can confirm that settings were NOT saving at all (100% of the time, not 50% of the time as previously stated).
Pro web designer, been building WP themes for a good few years, am positive there's no pilot error.
Also, unrelated (?) issue - I was working on a site the other day, had the plugin installed to test it out, everything looked normal, I hadn't touched any settings, then noticed the icons had switched from set 1 to set 2. No idea why.
