Problem with photo gallery!

I’m having problem with photos in gallery. I can upload photos without problems, but, when I’m editing photos problem start after 125. photo. First 125 photos in same gallery is ok, but after 125 I’m having problem with editing the title and reordering. I change title, and order of the photo, click on save the changes, but it doesn’t save. That happens in every gallery that have more then 125 photos, uploading is ok, but problem starts with editing, and that just for photo after 125.
Can you help me!!
