We have been having some errors on our DNN 3.3.7 forums.

1.  We have had our forums live for years, now we get an error everytime you click to go there.  If you goto www.multispecies.com and click on our forums you'll see it.  Here's what error it gives on the "page load exception" event from the log viewer.

We have also been having troubles with the times being off by nearly a day for over a year.  Not as big a deal, but we have checked the settings, the servers, everything.  Is there a fix to this or both of these errors?  Or do we need to restore to a couple days ago?  We don't want to lose all our posts. 

Should we upgrade to the newest DNN 4.8 and if so will we lose anything in the forums on the upgrade?  Or could it fix the times? 

Thanks

Can we upgrade to DNN 4.8.2 and keep all our posts?  And when upgrading to DNN 4.8.2 does the forums module automatically upgrade?  Or do we need to upgrade it separately, once we are at DNN 4.8.2?  And of course, we don't want to lose our posts todate.

Thanks,..
