Thank you very much! I appreciate all the support.
It seems that the only issue was with the logo in the header. That fixed the navigation.
Yes, there are many items which are not displaying. I have not modified any files since.
I have no caching plugin, none of these worked. I tried each one; under portfolio there should be the pages, I think theres probably about 8. The option doesn’t even show there are more than three images. I can clearly see that they are there, but it looks as if something in the new code/ update isn’t displaying the page numerations on the portfolio images page.
Alright, do I just re-download the theme to update it? I never updated a theme before.
