Posting Breaks across the entire Site

BBcode Error? M

I first reported it to xF thinking it was something else.

Once I disabled Vaultwiki, the site went back to normal. Heres the error I reproted on xF.com https://xenforo.com/community/thread...vwaddtag.84150

Users were getting the following error on the front end: The server responded with an error. The error message is in the JavaScript console.

Regardless, having VaultWiki enabled makes it so no one can post in PMs/Threads.

Fixed in the current ZIP. This occurred for replies to threads that had users who were subscribed via email, if the forum was also configured to allow BB-Code in emails.

Just download the current release again and it should be patched.

EDIT: Having an issue with file permissions right now. It seems the most important file for resolving this issue is not readable by PHP and is not being included in the download. Please bear with me while I investigate this.

Ah okay.

Just saw your edit.

I was wondering why the new download didn't fix it.

File permissions fixed. Some mounts were lost after server reboot last night. I will probably spend the rest of the day trying to find out why.

In the mean time, you should now be able to download a working copy of the ZIP.

Seems to have worked like a charm!

Now users can't save their signatures.

Code:

ErrorException: Fatal Error: Call to undefined method XenForo_BbCode_Formatter_BbCode_Filter::vwAddTag() - library/vw/XenForo/BbCode/Parser.php:208 Generated By: Kattz, 21 minutes ago Stack Trace #0 [internal function]: XenForo_Application::handleFatalError()

This happens when ever a signature is edited.

I have uploaded the latest zip RC3 pl1 and even ran the installer again.
I can not fix this issue. The error is exactly the same. Posting also breaks site wide. The file in the zip has this on line 208:
$this->_formatter->vwAddTag($tag, $tagInfo);
$this->_taglist["$tag"] = $tagInfo;

I dont know what is happening, but it still breaks.
php has been restarted.

Note that every time you see a vwAddTag error, the message should be different if it was supposedly fixed already. The reason is that for every kind of parser that gets added to XenForo, VaultWiki needs to add a class to extend that new parser too or a security vulnerability might open. Because of this, we decided early on during beta that it would be better to get a fatal error in these cases than to let users possibly make vulnerable posts. The idea was that we would start suppressing these errors for the gold release.

Once suppression is available, VaultWiki should be able to detect if the un-extended class might have a security vulnerability when used in conjunction with VaultWiki and instead just disable itself in those cases. This mechanism was supposed to be included as of RC 1 but apparently it wasn't working properly. I suspect it had to do with creating multiple instances of the BB-Code parser with different rules during save actions (on save: parse for quotes, @mentions, etc. then parse for email notifications). For these cases, I believe the error suppression is finally fixed in RC 4.

I've just enabled RC 4 for download, so you can see if it resolves the issue.

Yes, it seems fixed in RC4.
