Hello all,
I have just ungraded our 4 Moodles to version 4..0.1 and all has gone smoothly apart from one. I get the error - Unable to find a default lock instance when adding a recourse to any page. Debug info below. I have purged caches, deleted the contents of moodledata/localcache and moodledata/cache and also replaced the moodle/cache folder just in case there was some corruption to the files whilst upgrading.
- Moodle 4.0.1
- Server running Oracle Linux 8
- PHP version 7.4
- Theme Lambda
Thank you,
Nige.
