Since yesterday all blocks showing views output become inactive when clearing cache. After reactivating and assigning them to their regions again, the views blocks produce some output again but only a list of titles is shown. So I have to install my database backup to get the site running again.
Most blocks are set to be visible on frontpage only. The nodes and entities shown in the views blocks are using Field Group.
Yesterday I updated to field_group 7.x-1.2 and installed HTML Purifier 7.x-1.0. See copy of this issue at https://drupal.org/node/2078497
I am using drupal 7.23 and views 7.x-3.7.
Coud you give me some advice, please?
Thank you in advance.
