My store is installed on my Wordpress.org self-hosted site and has been working beautifully since first installed last July. I haven't made any recent upgrades to WP or to Ecwid. All I did today was put an item back into inventory that had been out of stock. Now the store doesn't appear. I have tried all of the fixes that were in the forum (replacing the line of ECWID code, deactivating then reactivating the plugin, checking the page ID in the wp/admin.options page, etc.) and nothing has worked. And the text that I had on the page before the store has now dropped down to the bottom of the page (it as in its proper place at the top under the menu bar before I tried the various fixes). The page is located at
