Thanks for all the continued input.
So, to answer some questions:
I had all mods complete and working for about a month before the problems showed up. After about a week, the problem seems to have mostly fixed itself. That is, the sidebars have started showing up again about 95% of the time. Perhaps they changed something on the server and have now fixed it - most of the time... Hmmm... Doesn't really make sense.
I don't know when ipage upgraded to 5.3. I can ask them if that is still a relevant issue.
I'm not sure if I can make changes in my CP without overwriting my config file - I'll have to test that out when I get back home.
Is Driv's fix still valid? If there is a chance it will fix my problem I will give it a try.
Think you.
