I”m having the same problem as well on all major desktop browsers with win7. Using the following in the header:
<?php add_modal_login_button( $login_text = 'Login', $logout_text = 'Logout', $logout_url = '', $show_admin = false ); ?>
The page does not refresh after logged in, I have to refresh manually to see the update. So far I’ve tried deactivating various plugins and defaulting back to the parent theme’s functions file, but I haven’t been able to phase it.
