The following error message was returned:

Column 'parentId' in where clause is ambiguous

Database is not currently up to date! Visit Tiki Installer to resolve this issue. If you have shell (SSH) access, you can also use the following, on the command line, from the root of your Tiki installation: php console.php database:update

The query was:

select `threadId`, `forumId` from `tiki_comments`,`tiki_forums` where `object`=`forumId` and `objectType`=? and `parentId`=? order by `commentDate` desc


  1. forum
  2. 0

The built query was likely:

select `threadId`, `forumId` from `tiki_comments`,`tiki_forums` where `object`=`forumId` and `objectType`='forum' and `parentId`='0' order by `commentDate` desc

Things to check:

  1. Is your database up and running?

  2. Is your database corrupt? Please see how to repair your database

  3. Are your database settings accurate? (username, schema name, etc in db/local.php)
