Images are uploaded but those are not avaliable in a form I have a problem with webform module and that too with my site only :(
When I add form field with image upload, photos are uploaded but when I check submissions there are empty places, only I can find this photo in FTP in path sites/all/webform/

When I add required field, so user can not go to the next page break
I choose file, format and weight is correct, I click upload a file, looks that is uploaded



I try to go to the next page break but it is impossible because appears a notice that this field is required and is empty...



I try to do in another webform created, without page breaks and another fields, but issue is the same.

In another drupal site in my server I don't have this issue. If you want to reproduce please go to my site:
vidicon.nazwa.pl/brodnica/zgloszenie_firmy

please fill fields with* and after upload photo in last field and try to go to next step. It will be not possible but I will have this image on my server in /sites/default/files/webform/...

BTW I try to create a another simple form with image upload field and the same issue occurs, permission I set the same as in other site where webform works properly. I don't have any ideas, but I need this webform to my site :(

Thank you in advance for help.
Case is resolved, issue appears in drupal 7.43 and 7.44, I last version - 7.50 works ok
