Hi,
I followed the advice that seems to be given for this problem, which is to change the permissions from 755 to 777 in the uploads file.
Solved my problem and the images are now uploading.
Just one quick question, I am slightly nervous leaving the permissions at 777 as doesn’t this leave the site far more vulnerable to attack???
And I did try and changing it back to 755 after one upload (As was suggested in one comment) but that created the same problem as before.
Thanks
Vanessa
