Hi there,
I modified our head_customer.tpl several years ago with links to our blog, facebook page and twitter page. We haven't had any problems until yesterday when a customer emailed us and was very concerned about the warnings she got when she tried to check out.
It freaked me out a little and I contacted our webhost. She told me it was the link to twitter that caused the warnings. So I removed it (I'm not sure if it was the link I have in the header or the social bookmarks add-on I had installed... but I thought it was more likely the change I had done rather than an add-on you pay for

). Anyway, I still have the links to our blog and facebook in the head_customer.tpl and now I'm wondering if they are causing the same issues. I asked our host, but never heard back. I guess they thought their job was done. And I can't see this warning myself.
Is there a way for me to check this? And does anyone know if links in the head_customer.tpl will cause issues when you move from http to https? Any help in this matter would be greatly appreciated, since this is all slightly beyond my grasp of understanding. I just don't want to scare off new customers (although she may have been an alarmist... especially considering that she tried to sell me on her website development company....

)
I will attach the screen dumps my customer sent me.
Thanks a million!
Oh, and here is a link to our site if you want to look at this header:
