I get the above message when attempting to add a .jpg
I am installing on windows7-64 with 3.5.1.
I have checked php.ini for file uploads/sizes
I have tried several images from small to large
I have run attrib -s -h -r /S on my entire apache tree
The apache tree contains the "uploads" folder
(this is my dev machine - only I use it and with full admin privs)
UAC is off
The file name is also missing from the error message I notice
but is accepted ok in the selector window.
I have tried deleting and re-installing 3.5.1 from scratch
I'm stuck - any suggestions please?
