I have a few broken albums I am trying to get rid of on this newly restored album and I am getting the following message posted to the browser. I have tried rebuilding all Thumbnails. The rebuild fails for about 128 items out of some 3107 items with an exception stack. I have also tried deleting caches to no avail. Any help would be appreciated.
Thanks
Error message when deleting broken album is:
An error has occurred while interacting with the platform.
The exact nature of the platform error is unknown. A common cause are insufficient file system permissions. This can happen if you or your webhost changed something in the file system, e.g. by restoring data from a backup.
