All Posts view kills dashboard

Hi folks –

Here’s what I did – changed the number of posts that display per page in the All Posts view in the dashboard from 50 to 999 (to get all posts to be listed so I can do a bulk edit)….. The resultant list (800+ posts) never displayed… my browser waited for more than 15 minutes before I forced an exit.

Now – I have to have a clean login to the dashboard to post – and I can’t try to access the post listing or it locks up my dashboard access again.

I’m not totally versed in database issues – so I am not going to tinker too much without guidance, so I don’t break it worse. I did log into my hosting cPanel and do a “check” and “repair” on the database … returned no errors.

URL is http://www.marleysmutts.com … theme is ThemeForest’s “Continuum”

Any guidance is most appreciated. I searched the posts here and either I’m not using the right search string, or I’ve created a unique problem (most likely the former).

Thanks in advance.

Bob
