Further to our conversation: checking these links on my installation
I was given this message.
The following strings are not defined in /home/tnzbaaq/public_html/u-tokai/moodle/lang/en/block_course_list.php
$string['configadminview'] = "";
Warning: main(../../config.php): failed to open stream: No such file or directory in /home/tnzbaaq/public_html/u-tokai/moodle/lang/en/hotpot.php on line 10
Does this help in your analysis of my problem?
