I try to upgrade from 2.2.9 to 2.5.2 and get the following error message:
It is impossible to downgrade mod_wiki från 2012061701 till 2012061701
Debug info: Error code: cannotdowngrade
- line 313 of /lib/upgradelib.php: downgrade_exception thrown
- line 69 of /mod/wiki/db/upgrade.php: call to upgrade_plugin_savepoint()
- line 664 of /lib/upgradelib.php: call to xmldb_wiki_upgrade()

- line 1586 of /lib/upgradelib.php: call to upgrade_plugins()
- line 394 of /admin/index.php: call to upgrade_noncore()
I have installed the wiki-module in the package 2.5.2 together with all other modules which do not give any error messages.
I can´t find any later wiki-module to download and install.
How do I solve this problem?
