I've run into an issue that I'm trying to save a new uploaded picture of a product and each time it kicks me out and I need to log back in. I've tried different pictures and using different browsers to log in with. I've extended my log in time to 6000 seconds and nothing is working. Any help is greatly appreciated.
I got the same problem, but i am not sure about the reason about.
i solved it after search in Internet and chcked diffrend tips.
My Session Cookie lifetime (System-configuration-Web_) was set to 'o' Zero.
After changing to 3600, the save was enabled again without exit from Backend !?
