Answer Box is getting disabled?

After some research I found that style of answer box is set to hidden. style=”visibility: hidden;“
Initially I thought this could be intended functionality based on role privileges. But even after giving full permissions to administrator and tried to answer a question from admin but issue still exists.
 
 
<div id=”wp-dwqa-answer-question-editor-editor-container“ class=”wp-editor-container“>

<textarea id=”dwqa-answer-question-editor“ class=”wp-editor-area“ name=”answer-content“ cols=”40“ autocomplete=”off“ rows=”2“ style=”visibility: hidden;“></textarea>

</div>

You can send me your site for further checking.

I have figured out the issue. One of the other plugin “Spider FAQ” is causing the issue.
