Package moodle-2.2.10-1.el6.noarch links to external PEAR library, but external PEAR-HTML library is not complete (as Moodle requires). My Moodle upgraded installation shows empty page because DHTMLRulesTableless.php is not found in the system. There is few symlinks in /var/www/moodle/web/lib/pear/HTML: Common.php -> /usr/share/pear/HTML/Common.php QuickForm -> /usr/share/pear/HTML/QuickForm QuickForm.php -> /usr/share/pear/HTML/QuickForm.php In original package, there is file DHTMLRulesTableless.php in moodle/lib/pear/HTML/QuickForm, but in EPEL repository, there is no DHTMLRulesTableless.php file in actual EPEL package(s): # yum whatprovides \*/DHTMLRulesTableless.php Loaded plugins: downloadonly, fastestmirror, presto Loading mirror speeds from cached hostfile * base: ftp.cvut.cz * epel: mirror.1000mbps.com * extras: ftp.cvut.cz * updates: ftp.cvut.cz No Matches found Bacause dependency is not met, Moodle does not work. I did not tested empty Moodle, but this does not matter. This package should not rely on php-pear-HTML-QuickForm-3.2.12-1.el6.noarch package until full requirements are met. I reported this for moodle-2.2.9 before (IIRC).
