Heya,

I’ve tried two different linux distros thinking that one of them may have an older module, but I continue to get this error when looking for the first time at the homepage of the jatc_orisite_j25.zip quickstart template. I’ve been at this 4 hours now, sorry if it’s a nub question – any recommendation appreciated. Thanks.

Heya,

Just recreated the bug on my 3rd distro – started Ubuntu Server 12.*, then Debian Squeeze, and now Turnkey Linux. Any help appreciated…

Heya, thanks for the lead. While I was in checking the code I noticed the imagecreatefrom* functions need php5-gd as described here:
http://www.cyberciti.biz/faq/ubuntu-linux-install-or-add-php-gd-support-to-apache/

It’s fixed with:
sudo apt-get install php5-gd
/etc/init.d/apache2 restart

Apparently this will fix the issue for users of Debian, Ubuntu et al 🙂

Thanks again,

Sean.
