I have configured "allow users to upload any file"
I might be wary of allowing users to upload any type of file. Might suggest you restrict this a bit more unless you have a real use case for any and all file types, sans any restrictions. ✌
Thank you very much @PitaJ . now it is ok. but i remember that i had same problem two days ago after configure ngnix and config. site was good also i entered some categories and soon suddenly i got above errors. i hope it wont give error again.
