my apologies in advance for the rather obvious question but have you searched for the text 'some text here' in your (or better all) template files? To be on the safe side I would also look through the translation files. The lines '<meta name="1" till "3" seem to be created in a loop so I would check the templace code for that as well.
The tekst: "Some text here" is just some dummytekst I use in this forum. The tekst "Some text here" are on the site the correct author, copyright, description, keywords. So it display the correct data under the dummy-data from eZ. But with meta name="0", meta name="1" and so on.
Translation is not an issue with the meta tag.
Site.ini contains what it is supposed to contain (We have used this feature in all other sites too...).
Page_head.tpl is linked in from pagelayout.tpl, and contains the correct data.
This is set up the standard way, like we have done in a number of sites, but this time it just do not work correct. Strange...
