I cannot find or click on this button using selenium webdriver java
<p>I cannot find this element on the page. I get <strong>element not visible Exception</strong>, clickable messages. 
I've tried by id, name , css selector, any xpath alternatives or other ways I can reach this element</p>

<pre><code>driver.findElement(saveBtn).click();
</code></pre>

<p>My html source code</p>

<pre><code>a class="btn btn--primary" href="javascript:void(0);" name="save" id="saveBtn_24ad66f5be91c"&gt;Save&lt;/a&gt;
</code></pre>
