[Mediawiki-l] "Old" text in articles

[Rudeladmin]

Hello,

I edited an article-text directly in the database via a script from a
SQL-Database-Manager. 

 

When i select the article inside the wiki it shows me the "old" article.
After klicking the Edit-Button the "new", extern edited, Text is shown in
the edit-interface.

After storing the article the "new" text is also shown in the wiki.

 

Why is the new text primal after the "wiki-internal" storing visible and not
directly after the "wiki-external" scripting?!

 

Thanks for your help,

Dennis Wolf
