Hat alles wunderbar funktioniert! Danke!

/* NUMBERED NAV MENU */

CSS:

/* NUMBERED PAGE NAV */
.page-nav { font-size: 1.35em; font-weight: bold; margin: 1em 0; padding: 0; overflow: hidden; }
.page-nav-intro { float: left; padding: .3em .5em; margin: 0 1em 1em 0; background: #ffffff; border: .1em solid #ccc; }
.page-number { float: left; padding: .3em .5em; margin: 0 .2em; background: #fff; border: .1em solid #ccc;  }
.current-page-number { float: left; padding: .3em .5em; margin: 0 .2em; background: #ffffff; border: .1em solid #ccc; }

Das ganze sieht auch wesentlich schöner aus als dieses Plugin.
