You have to activate it by editing /class/textsanitizer/config.php (check this file in your backup of the 2.3.2b version of your site).
That it got deactivated is some kind of bug:
The installation procedure for the upgrade should prescribe that all these kind of config files should be left out when updating by the complete package (see point 2)!
But in the first place these kind of textual config files should NOT be there embedded in the program files and directories.
Where is the xoops_data/config/ map for anyway!
But for me, there shouldn't be textual config files at all. These configuration parameters should be reformed to be embedded in the system preferences in some new categories (system - textsanitizer, system - captcha, etc).
