Found a fix that worked for me.
Open login.php in modules/mod_k2_login/tmpl and find these lines near the bottom of the file:
<li><a href="<?php echo JRoute::_( 'index.php?option=com_user&view=reset' ); ?>"><?php echo JText::_('Forgot your password?'); ?></a></li>
<li><a href="<?php echo JRoute::_( 'index.php?option=com_user&view=remind' ); ?>"><?php echo JText::_('Forgot your username?'); ?></a></li>
<?php if ($usersConfig->get('allowUserRegistration')): ?>
<li><a href="<?php echo JRoute::_( 'index.php?option=com_user&view=register' ); ?>"><?php echo JText::_('Create an account'); ?></a></li>
<?php endif; ?>
and change to:
<li><a class="forgotpass" href="<?php echo JRoute::_( 'index.php?option=com_user&view=reset' ); ?>"><?php echo JText::_('Forgot your password?'); ?></a></li>
<li><a class="forgotuser" href="<?php echo JRoute::_( 'index.php?option=com_user&view=remind' ); ?>"><?php echo JText::_('Forgot your username?'); ?></a></li>
<?php if ($usersConfig->get('allowUserRegistration')): ?>
<li><a class="regusr" href="<?php echo JRoute::_( 'index.php?option=com_user&view=register' ); ?>"><?php echo JText::_('Create an account'); ?></a></li>
<?php endif; ?>
