Hmm, do you have any modifications at all? There really isn't anything in the code that would prevent it from displaying on one page but not another.

If it comes down to it, you might need to open a support ticket so I can take a closer look. I can't really think of anything other than some type of modification that's preventing it's display.

Well, if what you mean by modifications is limited to adding, editing or removing UBB files then no, this is a clean upgrade. I did add two links to the header for the top menu which I had done in the prior version with no issues, I also added background color attribute to a table tag in the footer. Neither of those edits caused this as I removed the edited files and reinstalled the originals that came with the 7.4.2 zip file.

The custom islands I have are all ones I was previously using as well and they are working as they always have. I did try removing them (hiding) leaving only the Who's On Line island but that had no effect. To summarize, there is nothing different going on when the main forum view is selected than any other page. This is really odd! But everything else seems to be working properly for now. I no longer fear performing updates... it was easy.

Since this is an upgrade performed in advance of moving this web site and forum to a new host and server, should I just perform a fresh install on the new server and import my database and see what happens? It might also be a good idea to re-download the UBB zip file just in case something got corrupted in the process. If you want to investigate this I will fill out a support ticket but I cant do that until I get home and look up my license number.

I did look at your chat online stuff and that is an IFRAME so that wouldn't have any effect either way. you using the same method I had used for the chat online box.

If you want, you can go ahead and upgrade and if the problem persists after that, then I can take a look and see if we can't track it down.

He already did upgrade Rick.
That's what started this.

Whoops, I meant the server move. Once it's actually moved over and the database transfered, then we can take a look.

I performed a fresh install on my new server and pulled my database over. The problem does not exist with no custom files or my HTML header and footer inserts <--- forgot about those but again, those are present when every page loads too. I think I will begin my move and see how it goes.

There is a problem with my install though: I performed a fresh install and none of my custom files are on the server but my database has information related to them. If I am moving I need to copy over certain directories and files, or is it best to transfer everything, set my paths and file permissions and update the DB? I assume that would transfer the problem with it though. Sooner or later I am bound to figure this out!

You'll want to make sure you transfer your cache_builders/custom directory and then once everything is in place on the new server you can login to the control panel and rebuild the cache to force all your islands to be rebuilt.

Well, it is safe to say this is not a bug but I am guessing you all suspected that from the start. I have transfered my forums to my new server and the Who's On Line disappearing on the main forum list page problem is not happening.

This is not a fresh install by the way, I zipped up my current live forums directory and unzipped it to my new server, set the file permissions, imported my database and ran the install script.

All seems well. This doesn't explain what the heck is happening on the live server at the moment but I am glad it is corrected. Thank you to all who offered help!

Glad to hear it got sorted out.
