Hi All,

I am trying to upgrade 1.1.6 to 1.2.3 and get the following error when I go through with the upgrade:

Mahara: Site Unavailable A column of your database is using a collation that is not the same as the database default. Please ensure all columns use the same collation as the database.

I went thrugh the steps to convert the database to utf-8 as suggested but still get the same error.

Any help would be greatly appreciated.

Did you ever find a fox for this problem?  We're having the exact same issue on our Mahara uprade (v1.1.5 to 1.2.4).  Very frustrating!!

Sorry for the delay - the answer is still no.

I tried doing an incremental upgrade which was working until I tried to move from 1.1.8 to 1.2.0. Got this error:

Could not execute command: ALTER TABLE "artefact_blog_blogpost_file" RENAME TO "artefact_attachment"
Call stack (most recent first):

• execute_sql("ALTER TABLE {artefact_blog_blogpost_file} RENAME T...") at /var/www/mahara/lib/db/upgrade.php:909

So I tried to skip 1.2.2 and got the original error of this post. Very frustrating and am ready to give up.

Did you manage to get any help?

Hi Mike & Greg,

Are you sure you changed every column of your db to utf8?  I had to do a conversion like that a while ago and can't remember the exact details, but I found some notes I made at that time which might be helpful, it's basically a matter of dumping the db, changing *all* the latin1 instances to utf8, creating a fresh utf8 db and then restoring into that:

1. Dump db.
mysqldump --user=root --password='xxxxxx' --host=localhost --create-options -c -e maharaDB > maharaDB.latin1.sql
2. Replace 'latin1' with 'utf8' in the dump file
sed 's/latin1/utf8/g' maharaDB.latin1.sql > maharaDB.utf8.sql
3. Create a new utf8 db
CREATE DATABASE maharaDB2 DEFAULT CHARACTER SET utf8;
4. Load dump file into new db
mysql --user=root --password='xxxxxx' maharaDB2 < maharaDB.utf8.sql
5. Edit config.php to point \$cfg->dbname at maharaDB2

R.
