I am using a test environment to see if it is possible to upgrade my existing Moodle 2.5 to Moodle 2.6
However I am having problems with courses that have the subpage module in use.
There are 2 versions of subpage available to me the one that is on our current Moodle and is shown as for moodle 2.4+ And the current one on GITHUB this is for Moodle 2.6+
I have tried 3 methods of upgrade
1. Upgrade subpage from 2.4+ to 2.6+ before upgrading moodle from 2.5 to 2.6
2. Upgrade subpage from 2.4+ to 2.6+ during the moodle upgrade process.
3. Upgrade subpage from 2.4+ to 2.6+ after upgrading moodle from 2.5 to 2.6
After any of these methods or not upgrading subpage at all. When I try to access a course in Moodle 2.6 with subpage in use I get a message saying
Can not find data record in database table subpage.
