@Reconix Do you think this is stable and ready to merge?

PHP: 7.1.2
sql:5.6.35

Are ok but once you update sql to 5.7+ you get that horrible time issue where you've got to set nil.

php 7.2 + still needs proper testing.

The only other thing I could find, when trying to do a delete all in activities we get this

Error Number: 1292

Truncated incorrect DOUBLE value: 'long-value-here'

UPDATE `bf_activities` SET `deleted` = 1 WHERE `user_id` != 'long-value-here'
