repair alias in pdf exported to external site
I'm a long-time user (three years plus) beyond Apple Support on a Mac 10.10.3 who is still learning (I'm holding out for the all-expenses-paid two-week intensive boot camp at Apple headquarters) but here's my problem:
I'm publishing a large quantity of content (1,500+ pages) externally and to an off-site wholly-owned, operated by Blue Host web site set up with WordPress as a blog. I have taken my content and exported it in Pages to the highest-quality PDF and then posted it to this web page. But it can't be read by the end-user and shows up as an amorphous grey block.
Near as I can tell, it's because the aliases are broken. What this means to me is that the chain that all the software reads working together can't be followed back to the original. Am I correct in that assumption? I'm trying to figure out how to go back and find the aliases, repair them, or re-create a new and functional set.
Is there an available explanation, primer, instruction?
