This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
Existing installation/ upgrade of wt_spamshield¶
With version 1.1.0 we have introduced some new fields in the database (for spam logging). If you are upgrading from an earlier version of wt_spamshield < 1.1.0 please make sure to compare the database fields. In TYPO3 version < 6.0 you can do this inside the extension manager. In TYPO3 Version >= 6.0 you can uninstall and install the extension again or open the install tool and run the database compare tool.
In wt_spamshield 1.2.0 we have removed the configuration which can be set within the extension manager. All the settings are now available via TypoScript. We have built a fallback mechanism which also checks for configured values done within the extension manager. This fallback will be removed in future versions.
