Hello,
We recently upgraded configurable reports from version 2016020103 to 2019122000. Unfortunately, it broke all of our existing custom SQL reports that are using templates (400+ in total).
Any custom SQL report that is using a template is now displaying "No records found". All the pages for those reports (Custom SQL, Filters, Permissions, Template, etc.) do not display any data (no template code etc.). These reports were working fine before the upgrade.
When I turn on debugging mode, I see the following notice:
Notice: unserialize(): Error at offset 5004 of 8375 bytes in /path/to/moodle/blocks/configurable_reports/locallib.php on line 172
As I mentioned, this only affects existing Custom SQL reports that are using templates. It works fine for the other Custom SQL Reports that are not using templates and for any new report that is using a template.
Has anyone seen this before?
Thanks in advance!
