Hey Simon,
Thanks for reaching out to us and sorry to hear about this issue! I’ll help you figuring out what’s going on here.
I’ve tried looking for some info in the theme, but let me say that I couldn’t find updated info on the Saico theme you are using. Seems it’s a very old theme, right? Do you think it’s possible to contact the theme authors?
Can send over the page.php code from the Saico theme (using GitHub’s Gist https://goo.gl/yAYY8X or a similar service to share) so I can take a look, maybe I can find an easy fix for this issue, not sure about that.
Please let me know about it,
Best,
Nico
