Can't send files for review, unknown error

Hello! I have uploaded files (photos, videos). When I sign them for the curator and sales (title, tags), I cannot save. Writes an error, but does not write which one. The same is true if I try to submit for a review. I used to send no problems, now I can't fix it

You can start by contacting support@pond5.com which is faster than asking for help here.

Thanks!
