Dear xenforos! I am receiving the error message, that Image Magick is not enabled on my logs. I had IMagick installed some 8 months ago and checked with the server support, which assured me, that IMagick is installed on Xenforo. (See details below). Why cannot I enable IMagick in the option-attachments -screen? I recently upgraded to XF1.5 and upgraded relevant addon folders (Convert Image). Thanks TonyB.
