I am using MyIPB theme and i have a issue regarding login box. my login box always appears on left side of bottom when it supose to show on center with model box
You need to change the model settings, also check what is happening on other browsers/screen on your site.
this is how model is open
onclick="$('#quick_login').modal({ fadeDuration: 250, keepelement: true, zIndex: (typeof modal_zindex !== 'undefined' ? modal_zindex : 9999) }); return false;"
and browsers/screen same on everything
