Better install a ‘social share’ plugin.

I have no dea.. I never heard any BUILT IN WP feature named event… I searched wordpress event documentation and nothing found. can you provide a screenshot what you really meaning by “event”.

And one thing to be clear… In your question (first message) you didn’t tell that u have a child theme so I told to remove that. And in 3rd message, you told you have a child theme and I told in forth message,

active another theme then the delete btu will be showed

.
I work with self made theme (learning yet) and didn’t work with child theme but i believe the child theme still in the folder /wp-content/themes/child-theme. something like that. give it a shot.

It is because they are trying to do things illegal way. They used different method to make the menu center. here is the fix (not so stable).
Here it is

header nav ul {
    position: relative;
    float: none;
    margin: 0px auto;
    padding: 0px;
    list-style: outside none none;
    width: 880px;
}

deleted: left:50%, added width (add more width if add more item and delete some if delete menu item}

header nav li {
    position: relative;
    float: left;
    margin: 6px 0px;
    border-right: 1px solid #DDD;
    padding: 8px 20px;
    display: block;
    text-transform: uppercase;
}

deleted right: 50%;
As you see, no horizontal scroll bar. http://imgur.com/EMo9tpp

Contact with your domain provider now… Nothing to do with WP
