It sounds like something in your theme is preventing them from being centered. Usually they’re centered by default. Could I perhaps have a look at your website?
Stefan, as this site is still very much a work in progress I would prefer to send you a link privately. Can you provide me with an e-mail address to send you the link? Or, you can e-mail your address at wolferman@pteconsulting.com. Thanks for any help you can provide.
Thanks for including your e-mail address. I just sent you an e-mail.
