Something quite weird has happened on the site and I cannot put my finger on what the actual cause is... Content has gone missing from the site menu. The pages are actually still there, but they do not display on the site menu page.
I have noticed a few discrepancies on the webmasters page at Google - the bot was getting kicked out where it should have been allowed to enter. I thought that it was perhaps something to do with the accessibility module and how it handles the mobile bot, but it seems that this is not the case.
The page / module is running as expected on my locally hosted machine, but alas there are issues on the live page. I will try to update the "tweak" that I made on the module, but I thought that I had done that already. Time will tell whether this fix will indeed succeed.
As I am back to work tomorrow, development of the bluemobi theme and updated version of the module for Drupal v6 will become less intensive. Not that it has been that way recently with the move and all the other things that have been happening. Stay tuned to this site for further updates.
Update: Well, creating a new page seems to have solved this problem. Go figure!
