Problems updating from pre 1.3 version (10 posts)

    In a few test I have made upgrading from pre 1.3 versions to 1.3.3 when 'DB_COLLATE' and 'DB_CHARSET' are not utf8 causes major problems.

    After replacing the system's files with the new version files I noticed that text from the db is not correctly encoded. When I enter the correct values in the config file ('latin1_swedish_ci') the text is shown correctly but now the upgrade process and creating new blogs do not work. It seems that wpmu is not able to create new tables.

    Could not find any useful information while searching the forums :(

    Any ideas?

    Actually we just discussed this a few days ago a bit.

    Best bet would be to convert your databases to UTF8 and then run the upgrade. UTF8 would probably be better as you'll be able to handle non-"english" (I can't think of the right word) charsets.

    Thanks. The problem is I was never able to convert to UTF8 without destroying the db.

    Are you actually running a convert script or just flipping the dropdown for the charset within phpmyadmin? You actually have to convert the data to the new charset.

    edit: This should help.

    I was running a convert script but a different one. I'll give it a try.

    Thanks!

    Things have improved and now I can upgrade some blogs. However, some blogs that were there have diapered and I'm directed to the signup page.

    Just to report babk... it seems that the issue with the redirection to the signup page was dns related. The dns records were not updated for over a week!

    selad, did this resolve the odd characters in your blogger's posts?

    suleiman, in the sandbox yes. The dump file is more than 500mb so its not simple to edit it directly.

    @selad: I've just posted a guide to how I successfully converted to utf8 after many failed attempts.

    I hit the encoding problems following the upgrade to 1.3.3 from 1.2.5a. The database had been running since 1.0RC4, and the tables up till now used latin1 encoding.
