At some point, you probably did an update without running update_to_latest.php, and your database is missing support for Visual Confirmation. The Knowledge Base article on Checking for Visual Confirmation support in your database and templates
explains this, and has a script for testing just for the VC support items. It can also fix one of the possible problems, if you uncomment three lines within it.
This does a more extensive test:
RIGHT click on the link above, and select "save as". Save it to your local disk. You then upload it as "validate_phpbb_v22.php" to your PHPBB directory, and run it with your browser. The results will tell you what fields and/or tables are missing.
If anything shows up in red
, other than the database version number, copy the "bbcode version" of the report from the text box at the bottom of the page and paste into a reply here, so that we can see what the results were.
