AttributeError: 'array.array' object has no attribute 'replace'

[anonymous]

I was just trying to post my first blog on my new install, but it didn't create it. I'v tried with and without category as well.

Some idea were nice.

Than you, G.

#3224 closed as duplicate. Note that this ticket provokes the error by a simple GET on blog front page ('/blog').

Some googleing seems to point to errors in your MySQL setup. Specifically it seems that wrong collation will return byte/char array instead of strings through the Python driver.

You need to check ​trac:wiki:MySqlDb, and specifically the utf8_general_ci collation setting.

The closed duplicate ticket also seems to point to issues outside the fullblog plugin, so I'm closing the ticket as 'invalid'.
