= UPGRADE from Protector 2.x =
- remove two lines for Protector from your mainfile.php
- remove all files under XOOPS_ROOT_PATH/modules/protector/ via FTP etc.
- upload files in the archive (refer INSTALL)
- do "upgrade" Protector in modulesadmin
- add two lines for Protector into your mainfile.php
Note: "XOOPS_TRUST_PATH" for 3.0 instead of "XOOPS_ROOT_PATH" for 2.x
The old files should be removed. Precheck and postcheck are still needed but they are called now from the TRUST_PATH.
