I am still taking small steps to build my site, and I do not have it turned on, so I will leave out my url for the time being.
I am using XOOPS 2.0.16, and the default themes all work correctly. The theme fiblue3d, however, does not allow me to PM members. If I send test users a message through the system admin area, there is no way for users (or webmasters) to reply to messages in an inbox either.

Debug:

I have a feeling this issue has a simple solution, but I have not been able to figure it out. So far, I have uninstalled and reinstalled repeatedly. I have tried several ways, including allowing modifications, cloning templates, and yes, clearing the cache and/or template_c(except the index file). I have also taken permissions into consideration. Nothing works. Is this a problem with a file? Do I need to alter a line in a file? pmlite.php, an index.php file? Or do I have to abandon the theme?

There is an easy fix, right? What am I missing? Thanks for any help.
I'm sorry if this is covered somewhere else on the site or one of the other XOOPS related sites. I have looked hard and found no answers.

I suppose my post was not up to par with expectations and so it is ignored?

I am sure someone knows the answer to my problem. Where o' where is that someone?

check if this is in the theme.
FAQ:Where do I put the <{$xoops_module_header}> into theme.html ? .if you are having problems with javascript not working. that is one of the solutions. (the most common one).

Thanks Bandit-X!
That was indeed my problem. Simple solution.
Thanks for your time.
