With iOS11 it is not possible to upload photos taken with iPhone/iPad, anymore.
You recieve an error "Denied file extension".
First analysis result:
It seems Apple changed the file extension of camera photos from "JPG" to "jpeg". The later should be allowed, unfortunately our default ExtensionDeny setting includes "...|jpe|..." in the settings_sample.json and we do not check for extension with "^" and "$" bounds. So regular expression triggers here, as jpe is a substring of jpeg.
Solution:
Make full string regular expression match for extension by adding "^(" as prefix and ")$" as suffix to settings allowExtension & denyExtension.
Rationale:
We won't add this to the settings regular expression, as this would mean that admins have to update their settings in order to fix this bug.
FunFact & Workaround
It is possible to upload ScreenCaptures (Pressing HOME + ON/OFF button) as iOS then creates a *.PNG image. So a workaround could be to view the camera photo on device, then take screen snapshot and upload the snapshot PNG to 4Minitz.
