Cannot save page after migration [SOLVED]

Help / Discuss

After migrating my Xwiki to 11.1 I encounter this exception when I try to save a page.
Something I can do to fix this ?

Hi @barmeier this is related to some changes we bring on 11.1 on the notifications component.
We forgot at first to indicate the step for migrating it properly, the documentation is now available there:
https://www.xwiki.org/xwiki/bin/view/ReleaseNotes/Data/XWiki/11.1/#HIntroductionoftheEventStreamStore.

Hi surli,

the hibernate.cfg.xml is OK. But I found the ActivityStreamPlugin in the list of installed Extension.
Anything else I could do ?

4

Hi.
You need to remove ActivityStreamPlugin in the list of plugins in xwiki.cfg, but also it seems you have some Activity Stream leftovers in your WEB-INF/lib directory. All activity stream related jars should be removed.

I hope it helps.

If this is true then you should probably redo your install/upgrade since it means you haven’t followed the upgrade process and your instance may be corrupted. You should never unzip a newer version on top of an existing version. See https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Upgrade

Hi,
works like charm :slight_smile:
Thanks a lot

Hi Vincent,

I always use debian package upgrade. After the debian upgrade the upgrade wizzard comes up and I completed the setup.

Must I reconfigure things manual after debian upgrades ?

8

Ah ok cool.

No. But if you used the debian upgrade I don’t see how you could have the AS JAR in your WEB-INF/lib directory since we removed it from the XWiki distribution.

WDYM? Can you explain what you did precisely?

If you removed the entry from xwiki.cfg only then all is fine! If you had to remove some JAR then there’s a problem.

9

There was no JAR file on the disk removing the entry from xwiki.cfg was sufficient.
Sorry, my reply was a bit to short.

all good then :slight_smile:
