Fresh installation everything went fine but when I post……..

What are you trying to fix? Might help us help you if you didn’t make us guess. ??

If you’re talking about the unbroken lines, I would try putting in some spaces into your typing. WordPress and your browser have no way of knowing where you want line breaks in your text.

Did you type in that test post yourself? It looks like because you’ve just typed in one really long word it is stretching right across into the side bar area.

Try editing the test post and just putting in some random, but real text, not just one long word.

No normal person posts lines like that. Sorry.
That’s not a bug. Just make a post with some real text.

Im not making anybody guess lol Ide would have thought the problem was obvious.

Thank you for your help drmike and TonyGeer ??
