All fixed!
I found in the bug report list at the link above that someone recommended that using PHP5 instead for 4 would resolve this issue. My 1&1 server was running 4.4.9 and so I added a .htaccess file and forced it to use PHP5 (5.2.6 is running now) and everything works great. All the thumbnails that failed earlier are now created. This is what I added to my .htaccess file:
AddType x-mapp-php5 .php
AddHandler x-mapp-php5 .php
Too easy!
Just noticed that 3 files that failed were landscape ones where as the portrait oriented image successfully had a thumbnail created. All were 800×600 (or 600×800 in the portrait’s case).
I am getting the same error.
I tried uploading 4 new images to a gallery and it successfully created a thumbnail for the last file I uploaded but it failed on the 3 others. I tried deleting the images and uploading again and failed again.
I am using WP 2.7 RC2 and NextGen 1.0.0 RC2.
