Part I--After searching for the answers to my questions, I have noticed the adivce to upgrade my 4.8 version to the new 5.13 security version. Should I do this before worrying about the errors some of the people receive who try to upload pics?

Part II--I've had PP for over a year and no problems. Now, I've got 2 people who cannot upload photos, but many others still can and I can upload through admin for them. Here is the problem:

The first one has uploaded many pics before, and now gets this error:

Warning: imagecreatefromjpeg(): '/home/coordina/public_html/photopost/uploads/74/IMG_3020.jpg' is not a valid JPEG file in /home/coordina/public_html/photopost/image-inc.php on line 81

"Unable to create image [/home/coordina/public_html/photopost/uploads/74/img_3020.jpg]. Please contact system administrator"

When she creates a 'test' user, she is able to upload just fine.

The second one is new and gets this error:

Unable to create image [/home/coordina/public_html/photopost/uploads/277/2005_Layouts_034.jpg].
Please contact system administrator.

TIA!
