I have gone through the code of this module (version 7.x-2.11-beta2) and found there is an update hook 7006, which is not going to work if we are using date time field (unix timestamp) with field encryption option.
There is a query which is fetching all the id from table config of those field which are date field and assign a index on those field but once any date field using field encrypt settings on then this update hook will never going to fired and giving the below error
"Syntax error or access violation: 1170 BLOB/TEXT
column 'field_date_field' used in key specification without a key"
Fixed

It's likely this issue predates Contrib.social: some issue and comment data are missing.
This line $query->condition('f.data', '%' . db_like(' field_encrypt";a:1:{s:7:"encrypt";i:0 ') . '%', 'LIKE'); does not seem to work because of the space before and after. If we change it to $query->condition('f.data', '%' . db_like('field_encrypt";a:1:{s:7:"encrypt";i:0') . '%', 'LIKE'); it works properly.
