Undo edit causes DB error.

Revert the most recent edit.
Revert the reversion so you are again on the most recent edit.
The un-converted text should be restored.

I am working right now to correct this issue so the conversion should create a new edit for every page. This way if people lose content, they can just revert the conversion for that 1 article, and change the BB-Codes manually.

Reverting to the latest edit causes this error:

Code:

Thanks. In vault/tab/history.php, find:

Code:

		$last = $db->query_first("
			SELECT lastrevisionid AS revisionid
			FROM " . TABLE_PREFIX . "vault_revision
			WHERE revisionid = " . intval($revisionid) . "
		");

Replace with:

Code:

		$relative = $db->query_first("
			SELECT dateline
			FROM " . TABLE_PREFIX . "vault_revision
			WHERE revisionid = " . intval($revisionid) . "
		");

		$last = $db->query_first("
			SELECT revisionid
			FROM " . TABLE_PREFIX . "vault_revision
			WHERE dateline < " . intval($relative['dateline']) . "
				AND threadid = " . intval($threadinfo['threadid']) . "
				AND pending = 0
			ORDER BY dateline DESC
			LIMIT 1
		");

Now, when undoing the latest edit, I get redirected to:
/forum/redirect=no

Which does not exist.

Undoing the latest edit twice results in the same missing content.

I can only imagine this happening if you converted BB-Codes before you imported the edits. In this case, the un-converted edit may be further back in the list (1 more back?). Please check the revisions or use the compare tool to confirm.

This likely happened.

Can it be the the [div=float:left;width:50%;] code doesnt work in Vaultwiki 3.0.7? If so then it becomes very hard to find the correct version of the header. All my forum headers have this code.

That code doesn't work in VaultWiki 3.0.7. That was NuWiki's format and it had unresolved security issues for the past few years. However, that's the unconverted code you want to revert to. Then you can update it to this format manually I suppose:

Code:

[div] style="styles" | content [/div]

If all your headers have the same styles, it should be a little faster, since you only have to replace the

Code:

[div=float:left;width:50%;]

part.

Could you show me an example of how that works?

For example if I want to replace this:
[div=float:left;width:50%;]some text
another line
another line [div=float:left;width:50%;][/div]
[div=float:left;width:50%;]some text
another line
another line [/div]

Code:

[div] style="float: left; width: 50%" | some text
another line
another line [div] style="float: left; width: 50%" | [/div]
[div] style="float: left; width: 50%" | some text
another line
another line [/div][/div]
