Duplicate Posts By Accident
 

Has anybody else run into this on 3.8.0?

I didn't have this problem before but now that I have upgraded to 3.8.0 my members are noticing that sometimes when using the quick reply their post shows up twice.

Interestingly enough I think this problem would normally be avoided when the system checks for duplicate posts before inserting the post, however I have Xenon's "Prevent Doubleposting" hack installed.

Didn't want to hijack his thread since for all I know this is a separate issue. The problem is related somewhat to that hack however because the way the system normally works is:

1. A user posts.
2. VB checks for any recent posts with the exact same text and spits back an error message if it's a duplicate post.

With the "Prevent Doubleposts" hack, this changes somewhat.

1. A user posts.
2. PDP checks to see if the previous post in the thread was made by the same user and if so it merges the two:

3. Where VB would normally find the duplicate content, it now does not realize this because the post that just went through was merged with the previous post.

The would be duplicate post:

Is compared to (or not compared to actually, but for the sake of laying this out, is no longer identical to:)

Is not the same post as:

So the "Prevent Doubleposts" will automerge the two for the unsightly result of:

So does that make sense? Has anybody else noticed people having problems with their post going through twice with quick reply on 3.8.0? If so have you found out why?

The problem itself is not the "Prevent Doubleposts" hack. That's just making it worse. Fixing the root cause will make the "Prevent Doubleposts" hack irrelevent, which is good because I'd like to keep it enabled.

What could the root cause be though? Thoughts?

It looks like you need to allow vb to check for the duplicate post first and then allow the mod to merge the posts. You may have to change the hook location, but that is a question best asked of the developer.

I remember that being an option but for the life of me I can't find it. (Checking for duplicate posts). Do you remember off the top of your head where it is in standard VB?

To be honest, I have no idea. I've never had this problem so I've never looked into it.

Also, changing hook locations isn't necessary now that I think about it.

The main problem is that it's putting posts in twice in the first place which has nothing to do with that hack.

Make sure you have installed the vBSEO patch for 3.8.0 if you have vBSEO installed.
