Posts Taking Too Long to Schedule and Not Working

Hi,
My name is Cassandra Stout, and I can no longer publish, schedule, or save posts on my www.remarpro.com site. My wordpress.com site works perfectly fine, so I’m assuming this is a problem on the hosting end.

To reproduce this bug, take the following steps:
-open a new post
-write “test” or whatever text you want
-click publish immediately
-grey circle spins and post never updates

OR:
-click on previously-written post
-resolve blocks from html
-change the date to something in the future
-click schedule post
-grey circle spins and post never updates

OR:
-open a new post or a previously-written post
-change the text in any way
-click save draft
-grey cloud flashes and post never saves

Any help would be appreciated. I need to publish posts starting on Friday so that my readers won’t be disappointed. I can’t even post a “sorry for the delay” post, so they will be confused.

Thank you very much!
