...never seems to work

Step 1: I load my browser and get logged in just fine

Step 2: I can compose a post just fine

step 3: I click submit and the button greys out


step 4: then page refreshes with the submit button replaced by a publish

step 5: then when pressed the publish button greys out


but always just refreshes back to the previous publish page. Rinse and repeat the last two steps of clicking publish over and over and nothing happens.

what am I doing wrong?

edit: additional note, I can reply to other people's posts on my phone, just cannot create a new post
