I spoke with my host and it seems there is now only one install of PhotoPost on the database, and that is the one that is missing the admin CP link and upload link.
When I spoke with the supervisor she cycled through the 5 installs and the one that appears to work best was the one we picked. We then concluded that the other installs should be removed - only after that did I notice the missing links, however I wasn't expecting them to have actually removed the other installs, giving their ineptitude with this problem from start to finish.
So now I have two choices: ask you guys to reinstall it and incur a second installation fee, which I will have to try and charge to my host. Or secondly, reinstall it myself which I failed to do before relenting and asking you guys to do it properly!
What would you suggest? I'm not a happy bunny right now.
