a) The changes you refer to were made PRIOR to the problem occuring. I only purchased Photopost a week ago to begin with.
b) I had already tried switching to GD2 and it made no difference. That was actually the first thing I did, based on a suggestion I received from someone else before I came to this forum looking for help.
c) you continue to ignore the fact that PP Classifieds and Reviewpost on the very same site, installed at the very same time, DO NOT HAVE THIS PROBLEM and also use ImageMagick
d) I will have Imagemagick upgraded to 6.1.8 01 and see if it helps.
