Wow - now *here's* something new.
I'm working on my 2.5.1 site, and I have not touched the core files since I've uploaded them several months ago. I was working on the theme last week, and everything was going fine.
Today, I open her up to continue working on my theme files, and I cannot update them. I can open them, and edit them, but when I hit the "update" button, I am immediately returned to the front page fo the theme editor. Edits are lost, no changes are made, I'm just redirected to the from page of the theme editor.
So I make all my changes and FTP them. I got to edit an existing post. I make changes and click "Save" and I'll be damned if I'm not returned to the listing of all my posts. No changes saved...just redirected to the "Write>Posts" page. When I edit a Page - same thing happens - just redirected to "Write>Post" and all edits lost.
I have checked my server error logs, and there is *nothing* there - literally. It's a pristine white canvas. I switched the theme to default - nothing. I deactivated all plugins - nothing. I deleted everythign on the server, downlaoded a fresh copy of 2.5.1, and uplaoded. Nothing.
I'm out of ideas.
Would anyone know why it's doing this? I have never in my life seen anything like this happen before. I *could* upgrade to 2.6.1, but that would mean I'd need to check my theme files and all my plugins before I could do that - and I *just* got finished with it all being compatible with 2.5.1. I'd rather not have to do all of that again.
I'd love any advice or nudges on what I need to check. This is really bizarre. Normally when something "suddenly" stops working, I look at what it is I've done before - but that's not the case right now. I was messing with it last week and everything was fine. I start messing today, and it's not.
