Disappearing Threads

[colby2152]

All of a sudden, two days ago, my forum has been experiencing a strange issue with viewing threads in a board index.  It seems that third-level boards are most impacted.  An example can be found here: http://www.profsl.com/smf/index.php?board=1725.0

The board could show no threads despite there being five threads.  All of a sudden, a user could post a test thread in that board, go back to the index, and see all of the threads.  However, when the moderator moves a thread out of that board then all of the threads in the board index disappear.  The threads are still there but all users, guests, moderators, and admins cannot see the threads until a new thread is posted.

I thought lack of space on a partition drive of my server as well as running 2.0.6 (as opposed to 2.0.8 which just updated today) caused it, but it is still happening despite addressing both of those situations.  Help anyone?

Mods installed?

I did have an error earlier today from the Optimus Brave mod, but uninstalling that only removed the error and didn't address this problem.

You didn't answer the question, though. He used only a few words but answering that question might be more useful than you may think, as he/we/someone will be (hopefully) able to assist you that way. Otherwise it is simply not possible as your post is like "it doesn't work, please fix it for me and no I refuse to provide any further details because I just don't want to ". Dont take it personally, I tried to be a bit sarcastic to make you understand how you look like to everyone's eyes if you post like this. Moral is: please answer the question and provide as many details as possible so we can better assist you, will you?

I should have posted that I was via mobile and wasn't able to get the full list.

I have a laundry list of mods...

I wonder if there is a specific part of the SMF code that may be affected by a mod that I should be analyzing?

Updates: The boards affected appear to be ones in which a moderator has moved a thread from... and some of these boards, the second page of threads cannot be seen.  I have combatted this temporarily by instructing mods not to move threads (just lock them) and expanding number of threads viewed per board from 40 to 250.

As mentioned above, the boards affected appear to be ones in which a moderator has moved a thread from... and some of these boards, the second page of threads cannot be seen.  I have combatted this temporarily by instructing mods not to move threads (just lock them) and expanding number of threads viewed per board from 40 to 250.  Is there a particular file in the SMF code that affects how threads are viewed?

Having 250 topics per board can cause some performance penalty.

The list of topics per board is fetched in MessageIndex.php. There is, however, a bunch of conditionals that affect the output.
Could you please attach your file for us to check?

Also, I would try to disable forum cache entirely just to see if something changes

I figured which it is why it is temporary.  My board mods love it though.  Note that I increased it from 40 to 250 as a temporary means to address the issue at hand.

Thanks for taking a look at it.  It appears that only one of my custom mods (MGC Rewards System) affects MessageIndex.php and it is a simple one-liner.  I can't imagine that all of a sudden, as of August 1st, that mod decided to go asleep and break that line.

Also, I would try to disable forum cache entirely just to see if something changes

I have disabled cache.  Won't that affect performance?

[margarett]

I will add some extra load to you server, yes (stuff that isn't cached has to be loaded from the DB in every page load)

Did anything change with cache disabled?

Cache being disabled didn't change anything.  The problem is still there.

It has not been resolved.  Unfortunately, it's still a mystery.

Really a mystery...

I'd like to check it in place if you don't mind. Can you please PM me an admin test account? I'll also need access to the database...

Sure thing Bruno.  Check your Inbox.

For future reference, the issue was a wrong number of topics in boards. Affected boards had number of topics = 1 although there were several topics from that board.
When a topic was moved that total dropped to 0 and, as such, no topics were loaded.
"Recount totals" fixed the problem.
