I've run into a dead end trying to install an extension and am hoping for some guidance. The extension is Blackbird_ContentManager -- great extension and support overall, but I can't figure out what's going on here.
At first, I received
Blackbird_ContentManager data: current version - none, required version - 2.2.12
So when I run setup:upgrade, it got to Installing Data and then:
SQLSTATE: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`db_5798qz73hik`.`eav_entity_attribute`, CONSTRAINT `EAV_ENTITY_ATTRIBUTE_ATTRIBUTE_ID_EAV_ATTRIBUTE_ATTRIBUTE_ID` FOREIGN KEY (`attribute_id`) REFERENCES `eav_attribute` (`attribute_id`) ON D), query was: INSERT INTO `eav_entity_attribute` (`entity_type_id`, `attribute_set_id`, `attribute_group_id`, `attribute_id`, `sort_order`) VALUES (?, ?, ?, ?, ?)
Sometimes it'll make it it to the "Installing Data" phase of setup, but then I'll receive "Wrong entity ID" error. This is after deleting all relevant eav_* and blackbird_* tables/rows, as well as the entry in setup_module.
Obviously, I'm doing something wrong here, but I'm unsure what to do that I haven't already done and am getting increasingly nervous. Any help would be appreciated!
