I have a test moodle installation. I just installed 1.5.2+ over the top of 1.4.4.
I botched the copy and did not copy all files, then I ran admin, and found out that I made a mistake. Copied the rest of the files, re-ran the install. Everything seemed to work fine, I got the green messages for creating/updating the databases.
Now I am getting session key error message when I login to admin page, but not main index page. A few tables were not created. Timezone table and message table.
How do I cause moodle to check for the existence of tables, and if they are not there, to create them?
Otherwise, I am looking at a complete re-install.
