The import or the export? Do you manage to get your data from your site, or not even that? If there are problems with the export, you should raise them with wordpress.com

In this case, yes you do. Because you are not mapping a domain on top, using redirects, but changing the site’s url. This is alot like moving a site to a new url.

Hmm.. this sounds like a quite specific programming issue, don’t think there’s a plugin out there.
You would have to hook into the publish_post and update_post hooks and do a manual check if the publish date is in the future, and if not, return false.
For better user experience you could also introduce a js script which blocks the button as long as the date is not set to a future date.
If you are having difficulties with these tasks, I suggest getting a wp professional.

Please go to your backend, there you should see a settings menu item on the right bottom. When hovering on it, a submenu appears. This submenu has “Permalinks”. Go to that page and hit “Update permalinks”.

Then check if the issue persists.

There you go:

.page .page-wrap .content-wrapper, .single .page-wrap .content-wrapper {
    background: #fff2e6;
}

first of, in your custom css remove this

.entry-content a, .comment-content a {
    color: #fff !important;
}

and change this

a.blog-more-link {
    background: #000 none repeat scroll 0 0;
    color: #FFF; /* ADD THIS LINE */
}

2. The columns are all equal wide, the text is just not equal wide.

3. you can change the column width by adding the following code, and changing the second value:

.site-footer .widget {
    padding: 20px 20px;
}

I think WPML is the most used, and definately not depreciated multi language plugin. It is – however – a premium plugin.

You shouldn’t need to change the wordpress url. Just map domains on top of your existing setup. Also, this should be in the multisite forum.
