Jan 05, 2021Hello, we’re having an issue with installing Bloqs on a new EE6 installation.
This error comes up during the install process:
SQLSTATE[HY000]: General error: 1267 Illegal mix of collations (utf8_general_ci,COERCIBLE) and (utf8_unicode_ci,COERCIBLE) for operation '=':
SELECT * FROM information_schema.columns WHERE table_schema = database() and table_name = "exp_blocks_atom" and column_name = "data" and is_nullable = "NO"The database is set to utf8mb4_general_ci, so not sure where the other collations are coming from.
This is on a MySql 8.0.22 server.

I haven’t tested any add-ons on MySQL 8. For the time being your best bet is to downgrade.

Is there more to that error message? E.g. the call stack so I know what is generating that query?
BoldMinded (Brian)
Never mind, I found it.

Ah yeah, that makes sense. I can see what we can do there. I think MySql 8 is the default install on Ubuntu server 20.04.3 LTS.

This should be fixed in 4.6
