after searching diligently through the documentation for some hint on how to support multiple wikis on the same site (and finding none), I decided to try just untarring the distribution into a separate directory under the Apache home directory. Sounds safe, right?
i.e. I had been running with everything under htdocs/wiki, and now I created a htdocs/wiki2 by untarring, and ran the installation procedure again on the wiki2, and everything seemed fine, wiki2 was up. (I used a separate table prefix for wiki2, so the two sets of tables are distinct.)
However, now on the original wiki, I get
Fatal error: Call to a member function on a non-object in /usr/local/apache2/htdocs/wiki/includes/Database.php on line 1667
even deleting the wiki2 directory and restarting Apache doesn't make this go away.
How can I at least get the original wiki back, even if this strategy for multiple wikis won't work? Thanks,
Bob
