I think I am encountering a mysql strict error on Custom fields in Acymailing 5:
<Custom field> doesn't have a default value
When I look at table a8tg_acymailing_fields I indeed do not see default values for most fields. For example value:
| value | text | NO | | NULL | |
btw I have no idea why mysql strict is default, it doesn't help me with anything, but it still is on all webhosting servers.
