Fresh install of 2.5 but can’t make posts

I did a fresh install of 2.5 on my domain, install seemed fine. But when I click “write” or “edit” the page loads to 90% and then goes nowhere. I tried reinstalling with a new database but ended up with the same problem. I can move around everything else without any issues. I’m sorry I don’t have an error for this, but I’d really appreciate some help .. thanks.
