Can't get TAO working with Moodle through LTI
I'm trying to get TAO to work with Moodle to deliver a test. I've configured everything according to the manual, but I keep getting a blank screen in Moodle.
TAO and Moodle are both configured on the same webserver. The logfile on the website keeps returning this error:
[Tue Jul 18 21:05:18.747914 2017] [lsapi:error] [pid 273436:tid 140424486647552] [client 188.8.131.52:50761] [host www.haste.nl] Backend fatal error: PHP Fatal error: Cannot redeclare class OAuthException in /home/deb29122/domains/haste.nl/public_html/tao/tao/lib/oauth/OAuth.php on line 0\n
Anybody knows what's going wrong?
Thanks in advance.
