Some issues

First time in the forums so first of all hello everyone! and thanks for such a great CMS.

anyway, firstly i can’t leave blank lines, however much i try to and i don’t know if its a bug, i read somewhere that its part of the system to get rid of ‘unnecessary’ html, but what if we need those lines? For now i’ve settled with increasing line spacing to make things less cluttered.

also, i am having a cookie problem i think, my wordpress is logged in in the admin panel, but logged out on my website, so i can’t view drafts, etc. If i need to leave a comment on my blog instead of via the admin panel i need to type in the details as a guest.

another problem, started happening recently, my images are not linked to the full image, its not linked to anything i need to manually do it when i add an image.

when i center images it refuses to sometimes, captions don’t display like it should below the image, they display in plain text below it.

i don’t know if all these issues are with 2.7 but i need to fix these. thanks in advance.
