When I upgrade I get the following error which I can't understand:

Additional information about this error:

MySQL error!

Duplicate column name 'bloguser_perm_media_upload'(Errno=1060)

Your query:

ALTER TABLE evo_blogusers
MODIFY COLUMN bloguser_blog_ID int(11) unsigned NOT NULL default 0,
MODIFY COLUMN bloguser_user_ID int(11) unsigned NOT NULL default 0,
ADD COLUMN bloguser_perm_media_upload tinyint NOT NULL default 0,
ADD COLUMN bloguser_perm_media_browse tinyint NOT NULL default 0,
ADD COLUMN bloguser_perm_media_change tinyint NOT NULL default 0

From which version are you trying to upgrade? 0.9.1, right?

I cannot reproduce the problem here.. have you tried upgrading before? Have you manually changed your DB?

It's strange that the bloguser_perm_media_upload already exists.

I upgraded before from 0.9.1 to 0.9.2 and now I'm trying to upgrade to 1.8.5

I'm following the instuctions in the document "Upgrading from 0.9.x to 1.8.x AND "Upgrading from an older version"

kskhater, using the dump you've sent me I cannot reproduce the problem (after having removed the "evo_plugins" table from the dump, but which triggers another error earlier and you've probably have left it in there accidently - I've commented out lines 361-375 with a "#" for it).

Please try it again.. it should work.

You said: "I've commented out lines 361-375 with a "#" for it).

where're these lines located. Are they in the SQL-DB?

Thanks

In the dump you've sent me, yes. But it would cause another error, if you would use the dump as-is: "Table evo_plugins already exists"
