How to delete login or register form from ask question form

If you want to remove or edit the login form on the ask question page, you can open the question-submit-form.php in the plugins > dw-question-answer > templates folder then find the line 85.

<?php if ( is_user_logged_in() ) : ?>
		<div><?php _e( "You doesn't have permission to post a question", 'dwqa' ) ?></div>
	<?php else : ?>
		<div class="dwqa-answers-login">
			<div class="dwqa-answers-login-title">
				<p><?php printf( __( 'Please login or %1$sRegister%2$s to submit your answer', 'dwqa' ), '<a href="'.wp_registration_url().'">', '</a>' ) ?></p>
			</div>
			<div class="dwqa-answers-login-content">
				<?php wp_login_form(); ?>
				<?php do_action( 'wordpress_social_login' ); ?>
			</div>
		</div>
	<?php endif; ?>

Note: If you don’t want to override this custom in the next updates, you should
Go to your theme folder (wp-content/themes/[theme-name]), and create a new folder, named it “dwqa-templates”. Inside your new folder, copy the question-submit-form.php file and paste this file into the “dwqa-templates” folder.
Now, open up the new file in notepad or any code editor, and custom this file.
