I have looked for other threads that point to this issue but the only one that I have found was the one pointed out by Bob:

The first couple of posts discuss the causes and a possible solution but I am not sure what it is they actually did here.
I think the best solution for me is to ask my friend (I am doing this project as a favor) to get a refund from his iPage host and start all over again with a proven host that works with MODx installs.
Right now the manager login, Quick Manager and MaxiGallery functions are not working properly. I built this site locally using MAMP first and everything worked perfectly then.
I have contacted the host tech support but real solutions seem to be lacking. My "ticket" to more advanced support investigations have not come through...
Update: I called iPage tech support on the phone and got through instantly. The advice I got was to wait until the "second level" support guys address the support ticket. This might take 24 - 48 hours. I guess I will wait and see if they can find anything...
