[Semediawiki-user] Installation problem

[Dmitri P. <dmi...@gm...>]

Hello!

I have a MediaWiki 1.9.2 (language is Russian) and want to install
Semantic MediaWiki 0.6.

When I go to the page "Special:SMWAdmin" and press the "Initialise
tables" button, I get the following error message:

"Error in function SMW::MakeSemanticTables. MySQL returned: '1044:
Access denied for user 'wikiuser'@'localhost' to database 'wikidb'
(localhost)'".

However, the user "wikiuser" has all permissions on the database "wikidb".

How can I fix this error?

TIA
