Re: Site broken after 4.3-> 5.0 upgrade (search not working)
Hi Eric:
Please, upgrade to Tiki 5.3 instead, while ensuring that you re-set the connection to the database from the tiki-install.php script.
Follow the steps from here:
http://doc.tiki.org/Upgrade#Fix_the_encoding_issue
And report back if you still have issues after that.
Hope this helps.
