So did disabling tha hooks fix the original issue?

I've had this happen when there is a hook firing twice, usually due to a plugin. You need to move the function to a hook like global_start where it only runs once per page... This way it never gets re-declared.

No.

So we've enabled the hooks again.

We still get the double posts (but have enabled double posts checking so that we get the "Updated:" and silver line separation between two identical posts that are then put in one single post).

We also still get the notice if "Do you want to navigate from this page".

It's driving us nuts!!!

When you disable the hook/plugin system you are disabling all additional products that you may have added to vbulletin.

Because most modifications use the hook/plugins system, your modification 'Helpful Answers', should not run. That is the whole point in disabling the hooks/plugin system -- to see if you board works under a default setup. :)


This appends the current post to the last post if the last post was within certain time limits. It does not check for 'duplicate posts' more like "consecutive posts by the same poster".


---------------------------------------------------

(REFERENCE)
*Check Error* = Check to see if: "Do you want to navigate from this page" does not appear.

1.) Shut off hooks/plugins. *Check Error*.

2.) Fix any JavaScript errors on your page as this will certainly create problems with the ckeditor as @Cag Cheechdog suggested. This will cause the problem you are seeing under the right circumstances. After repairing the JavaScript errors, *Check Error*.

3.) At this point vbulletin should be working and *Check Error* should not exist. If the problem still exists then stop here and obtain further assistance.

4.) Re-enable the plugins/hook system. Disable, all non vBulletin products -- this is all the modifications you have added to the board. Then *Check Error*. If everything is working well, then continue, else stop and obtain further assistance.

5.) Enable Helpful Answers and *Check Error*. If all is well at this point then the problem is due to one of your other products that you have added. You will have to enable them one by one to find which product is causing you problems.

This is really just a summary of all the great suggestions given above by the members of vbulletin.org, but it seems you missed the overall picture, which is why you came full circle. I hope this gives you a better picture of the troubleshooting steps. :)

I am tired, I am going to bed. :)

I actually did follow your instructions by for instance turning off hooks and "check errors"...

Now, I found errors after disabling hooks. So went back here asking for further assistance.

Enabled hooks, "checked for errors" to find that the problems are still there.

We haven't got any non vBulletin products installed nor any modifications.

Yes, Javascript errors were mentioned in this thread, but not really how to FIX them!

This is why I went here, asking for your help...

Did you disable all plugins via the config

Disable plugins via config if this fixes the problem enable plugins again via config, then disable one plugin at a time until you find the problem one

To temporarily disable the plugin system, edit includes/config.php and add this line right under <?php

To enable plugins again just comment out the line
Use notepad++ to edit any files

Yes that was covered in post #2 and answered in post #10

Did you try the fix I mentioned here?

I PM'ed the link to the owner but he said he couldn't see the thread even after having logged in...

What is even more weird is that we've enabled the double posts checking which seems to work.

Here's an example from the forum:

HOWEVER, when I post something, I get the "Do you want navigate from this page" notice, and it submits two posts after eachother; i.e. without the separator and therefore NOT in one post.

You still have not specified your PHP version. :)
