Are you by chance running the same plugin?
No, tried running wordpres with only NextGen Gallery installed (no other plugin) but problem was still there.
since upgrade to latest version (1.9.8)
Same scenario for me, was working until I did an update of wordpress and NextGen to the latest version.
Thanks for the fast help!
Your code is working. At least I will be able to post a gallery 🙂
