I did a completely fresh upload of 1.9 (previous version was 1.5). When launching the install process after uploading the files, however, the webpage opened in Firefox with this message in a pink box:
"DB type: MYSQL not supported by XMLDDB"
Reverting to the 1.5 version of Moodle, everything functioned normally. However, I really would like to upgrade as I know there are security issues in older versions of Moodle.
"This issue seems to be with the non-compatibility of scripts with the existing tables on moodle database.You can refer to http://docs.moodle.org/en/XMLDB_preliminary_notes or support of moodle for the fix."
However I found nothing that referred specifically to this problem/error message, and all-in-all the language used to explain XMLDB/MYSQL compatibility was way beyond me.
Can anyone help?
