I have just encountered problems with an updated version of Ouwiki. Last year I was using moodle 1.9.9 and a version of ouwiki that I downloaded from cvs on 19th July 2010 (version.php does not give useful information about the actual module version unfortunately). As part of a general upgrade of the system to v1.9.12 I downloaded ouwiki.2.5.zip from the googledocs site and installed this into moodle/mod. I loaded the 1.9.9 database and all seemed to be well but I neglected to check that the user pages created by ouwiki were still present – after all I had done other moodle version updates and Ouwiki updates in the past without any hitches, and the forumng updated fine. However, now that the code is in production I find that not only have all the existing Ouwiki activities lost their data but an attempted restore from a course backup of only Ouwiki activities succeeds nominally but fails to restore any information. The same backup restored into a system using the previous year's code works fine. Has anyone else come across this problem? Is there a workaround? Short of jettisoning the v2.5 code and returning to the old code base I cannot think of a solution.
