Some update:
I installed the software from WordPress.org on my server and imported the blog from blogspot.com flawlessly.
So I decided to remove all post's and pages from LetterDetteke.WordPress.com and start over.
The result is:
Goshdarnit!
Something has gone wrong with our servers. It’s probably Matt’s fault.
We’ve just been notified of the problem.
Hopefully this should be fixed ASAP, so kindly reload in a minute and things should be back to normal.
After some time my dashboard appeared again :-) everything empty.
I imported again from the blogger address and it hangs again at 318 of 362 posts.
Comments are imported, but posts content is still missing.
I hope WordPress.com Staff can assist? or stick to Blogger...?
Thanx in advance.
