Blank article pages when using forum with existing threads

Blank article pages when using forum with existing threads

Earlier, I used the Lite-version and everything was fine until I switched to Premium (3.0.6).
Now, when I try to access the default namespace associated with existing forum (http://wiki.rotarycars.ru/showwiki.php - link on the left) I see a list of threads-articles that are empty on opening (contrary to the contents of the database, which has all the info).

At first I thought it was a problem because of the language, but English-language articles that I create does not work either

If you uninstalled Lite first, rather than upgrading, this may be the reason. Go to AdminCP > VaultWiki > Wiki URL Manager > Rebuild Page URLs.

Firstly I tried to run the upgrade script, but the "Proceed" button takes me back to the upgrade_lite.php (just like the simple page refresh), and I decided to try reinstalling the product.

After fixing this bug, the newly created articles work well (even with cyrillic names), but the old still does not work, even after Page URL rebuild...

Also, I tried to change thread title from Cyrillic to English manually via database (to make sure that this is not a problem with the charset), but it did not help

It's very strange. I compared the two threads and posts belonging to them in the database.
They are identical (only the first post from the new thread has an empty value in the "htmlstate" field; in the old topic - htmlstate is "on_nl2br" everywhere; but the database does not allow me to select a blank value to test it).

One thread works fine, the other - no

Lite did not have support for Cyrillic names. Because titles are mapped to URLs in a separate database table, simply editing the thread table in the database will not help. You will have to manually rename the pages in the following manner:

Go to the forum containing the old articles.
Double click the title of the problematic articles.
In the pop-up editor, change the title so that it uses the correct Cyrillic characters. Check the box not to redirect the old URL (it was broken anyway).
Save, and the article should now be available.

I tried to change the titles through the forum (as you wrote) and through the database (manually via phpmyadmin). Even change the Cyrillic titles to English. Then clean Article Post Cache and rebuilding URLs. But it does not help

If I try to create a new article with the name of the existing-old (blank), I just moved into edit screen. But the text field is still empty...

...
Seem to understand the problem.
The tables vault_article and vault_revision has no information about old topics, they are empty. How I can fill them?

OK, I've found. It just does not fill the articles and revisions tables when I assign Forum to the Namespace.
This action drops the error:

Code:

Well, the new error has come... the same action:

Code:

Temporary fixed it by removing the "!VAULT_40X_COMPAT" condition for the "LEFT JOIN " . TABLE_PREFIX . "thread" , changed the namespace forum to temporary forum and back to working one, rebuilded the URLs and it started to working!!

Okay I've fixed the errors you reported which were preventing the forum updates, so closing this. As for the articles being empty, this is expected when changing encoding methods (no Cyrllic support to Cyrillic support). It is also expected that the change is difficult to propagate across the database, but it looks like you have figured it out. We hope to simplify changes like this by separating the wiki from threads in version 4.
