ES Unable to Parse Server

Hi, I have seen this is a common issue. We are getting this error on some picture uploads from a mobile device to Easysocial in the frontend. We do not seem to get the error form desktop. Also some photos are fine and others are not. We have tried all the solutions that have been suggested before and none have helped.

We cannot work out why some pictures have this error. We have uploaded larger images without any issue then the ones causing the problem.

We have admin tools installed and have played with that as that has been mentioned but even disabling this component did not resolve this issue.

Any ideas would be very much appreciated.
Many thanks Mike
