Topic: LuxCal 4.7.0 - No thumbnails visible after upgrading
There is a flaw in the upgrade script. In the upgrade script the thumbnail privileges in the user groups are not initialized. The result is that, when upgrading, all existing user groups in the database have the Thumbnail privileges set to a non-existing value, which results in no privileges at all.
- Go to the admin's User Groups page. A number of PHP notices will be displayed. Ignore these messages.
- Edit each user group and set the Thumbnail privilege to one of the values from the drop-down menu.
After going through the steps above, there are no further adverse effects on the functioning of the calendar itself.
Only the upgrade script has this flaw; new installations are fine.
