site crashes when trying to load posts, contact link disabled

For about the past week I have been unable to access posts. I have tried to contact Craigslist, but contact link is disabled. I have seen that the filter which limits the number of posts in a category is gone. I see it will say total posts are in the thousands on some categories, and prior to populating the posts, it crashes the browser. I use an iPad and it crashes both the Safari browser and Mercury browser.
