I have been facing a problem it has occurred the second time. Here the problem description
After posting / publishing an article. If i go on to publish another article the first article just disappears completely does not go in to draft neither does it reflect on the site anywhere. It completely vanishes the only work around i found was to re-post or republish the whole document again.
We did not face any issue like this before. After recently updating the theme the problem has arise.
Please let us know how we can assist. As this problem is time consuming and outright rework over over again.
Try disabling your cache; try disabling all plugins except visual composer.
Try switching back to twenty-fifteen theme see if you can save posts.
Check to make sure you re-save permalinks; check to make sure your dbase is not overloaded, or if you have exceeded the storage space on your account, etc.
Try optimizing your WP database.
Try saving a draft post; then make sure you see the “post saved” message at top; then go to your “all posts” and see if there (be sure to make note of proper date setting on your post that you’re not saving it into the past where it would be buried on the index).
That would be my suggestion.
Worst case, reinstall theme and see if problem persists.
