Hi,
I have a similar issue to the one posted at
www.joomlaworks.net/forum/k2-en/42599-item-upload-image-are-all-the-same-sizes where k2 is not resizing the image for _XL, _M, _S, etc. All images are the size of the original.
I've not hijacked the other post because his problems seem to stem from an upgrade whereas I think mine are to do with the way I have set a server up.
I've set up a new apache 2 server on a VPS and moved across my site from a home-hosted server. At this site the resizing worked.
On the new VPS (running ubuntu 14.04 with apache 2(Apache/2.4.7 (Ubuntu)) and php5(5.5.9-1ubuntu4.11)) all images remain the size of the original.
I've set up a new joomla instance and installed K2 to see if the problem was the way i migrated across to the new server, but the problem persists on the new test install
Can anybody think of what might be missing with my Apache2 or PHP5 install that would prevent K2 from resizing the images?
Cheers,
Liam
