Hi and thanks for your fast reply.
I have tried to do as described but it won’t work.
Using a pre-existing subdirectory install:
I can not find this box under General/Settigs:
In the box for Site address (URL): change the address to the root directory’s URL. Example: http://example.com
Click Save Changes. (Do not worry about the error message and do not try to see your blog at this point! You will probably get a message about file not found.)
You could get admin access to my site, If you want to look at it.
Regards
Boris
