                    <b>For videos:</b> <i>Method 1 - </i> Do you already have a URL to the video you want to embed in a post, page, or even a widget? All you have to do is paste it on its own line, as shown below (including the http:// part). Easy, eh?<br>
                    <i>Method 2 - </i> If you want to do some formatting (e.g. add HTML to center a video) or have two or more videos next to each other on the same line, wrap each link with the <code>[embedyt]...[/embedyt]</code> shortcode. <b>Tip for embedding videos on the same line:</b> As shown in the example image below, decrease the size of each video so that they fit together on the same line (See the "How To Override Defaults" section for height and width instructions).
                </p>
                <p>
                    <b>For playlists:</b> Go to the page for the playlist that lists all of its videos (<a target="_blank" href="http://www.youtube.com/playlist?list=PL70DEC2B0568B5469">Example &raquo;</a>). Click on the video that you want the playlist to start with. Copy and paste that browser URL into your blog on its own line. If you want to have two or more playlists next to each other on the same line, wrap each link with the <code>[embedyt]...[/embedyt]</code> shortcode.
                </p>                
                <p>
                    <b>For channel playlists:</b> At your editor, click on the <img style="vertical-align: text-bottom;" src="<?php echo plugins_url('images/wizbuttonbig.png', __FILE__) ?>"> wizard button and choose the option <i>Search for a video or channel to insert in my editor.</i> Then, click on the <i>channel playlist</i> option there (instead of <i>single video</i>). Search for the channel username and follow the rest of the directions there.
                </p>
                <p>
                    <b>Examples:</b><br><br>
                    <img style="width: 900px; height: auto;" class="shadow" src="<?php echo plugins_url('images/sshowto.png', __FILE__) ?>" />
                </p>
                <p>
                    Always follow these rules for any URL:
                </p>
                <ul class="reglist">
                    <li>Make sure the URL is really on its own line by itself. Or, if you need multiple videos on the same line, make sure each URL is wrapped properly with the shortcode (Example:  <code>[embedyt]http://www.youtube.com/watch?v=ABCDEFGHIJK&width=400&height=250[/embedyt]</code>)</li>
                    <li>Make sure the URL is <strong>not</strong> an active hyperlink (i.e., it should just be plain text). Otherwise, highlight the URL and click the "unlink" button in your editor: <img src="<?php echo plugins_url('images/unlink.png', __FILE__) ?>"/></li>
                    <li>Make sure you did <strong>not</strong> format or align the URL in any way. If your URL still appears in your actual post instead of a video, highlight it and click the "remove formatting" button (formatting can be invisible sometimes): <img src="<?php echo plugins_url('images/erase.png', __FILE__) ?>"/></li>
                    <li>If you really want to align the video, try wrapping the link with the shortcode first. For example: <code>[embedyt]http://www.youtube.com/watch?v=ABCDEFGHIJK[/embedyt]</code> Using the shortcode also allows you to have two or more videos next to each other on the same line.  Just put the shortcoded links together on the same line. For example:<br>
                        <code>[embedyt]http://www.youtube.com/watch?v=ABCDEF[/embedyt] [embedyt]http://www.youtube.com/watch?v=GHIJK[/embedyt]</code>

                                    Use embed caching to speed up your page loads. By default, WordPress needs to request information from YouTube.com's servers for every video you embed, every time a page is loaded. These data requests can add time to your total page load time. Turn on this feature to cache that data (instead of having to request for the same information every time you load a page). This should then make your pages that have videos load faster.  It's been noted that even small speed ups in page load can help increase visitor engagement, retention, and conversions.

                                    Use embed caching to speed up your page loads. By default, WordPress needs to request information from YouTube.com's servers for every video you embed, every time a page is loaded. These data requests can add time to your total page load time. Turn on this feature to cache that data (instead of having to request for the same information every time you load a page). This should then make your pages that have videos load faster.  It's been noted that even small speed ups in page load can help increase visitor engagement, retention, and conversions.

                <h3 class="bold">Support tips for all users (Free and PRO)</h3>
                We've found that a common support request has been from users that are pasting video links on single lines, as required, but are not seeing the video embed show up. One of these suggestions is usually the fix:
                <ul class="reglist">
                    <li>Make sure the URL is really on its own line by itself. Or, if you need multiple videos on the same line, make sure each URL is wrapped properly with the shortcode (Example:  <code>[embedyt]http://www.youtube.com/watch?v=ABCDEFGHIJK&width=400&height=250[/embedyt]</code>)</li>
                    <li>Make sure the URL is not an active hyperlink (i.e., it should just be plain text). Otherwise, highlight the URL and click the "unlink" button in your editor: <img src="<?php echo plugins_url('images/unlink.png', __FILE__) ?>"/>.</li>
                    <li>Make sure you did <strong>not</strong> format or align the URL in any way. If your URL still appears in your actual post instead of a video, highlight it and click the "remove formatting" button (formatting can be invisible sometimes): <img src="<?php echo plugins_url('images/erase.png', __FILE__) ?>"/></li>
                    <li>Try wrapping the URL with the <code>[embedyt]...[/embedyt]</code> shortcode. For example: <code>[embedyt]http://www.youtube.com/watch?v=ABCDEFGHIJK[/embedyt]</code> Using the shortcode also allows you to have two or more videos next to each other on the same line.  Just put the shortcoded links together on the same line. For example:<br>
                        <code>[embedyt]http://www.youtube.com/watch?v=ABCDEF&width=400&height=250[/embedyt] [embedyt]http://www.youtube.com/watch?v=GHIJK&width=400&height=250[/embedyt]</code>
                        <br> TIP: As shown above, decrease the size of each video so that they fit together on the same line (See the "How To Override Defaults" section for height and width instructions)
                    </li>
                    <li>Finally, there's a slight chance your custom theme is the issue, if you have one. To know for sure, we suggest temporarily switching to one of the default WordPress themes (e.g., "Twenty Fourteen") just to see if your video does appear. If it suddenly works, then your custom theme is the issue. You can switch back when done testing.</li>
                    <li>If your videos always appear full size, try turning off "Responsive video sizing."</li>
                    <li>If none of the above work, you can contact us here if you still have issues: ext@embedplus.com. We'll try to respond within a week. PRO users should use the priority form below for faster replies.</li>                        
                </ul>
                <p>
                    Deactivating the No Cookies option has also been proven to solve player errors.
