What version of ioBanana are you using ?
- If it's ioBanana v20 (the latest release of the 1.x branch), you should upgrade to ioBanana 2 release 1 (the first release of the 2.x branch). ioBanana v20 is old and unsupported now.
- If it's ioB2, you should read
the FAQ. It will explain you why you can't use all the features of the rules system atm.
In all cases, you should read
the posting guidelines.
Edit: SITE RESCAN [filename] where filename is a checked file (*.rar usually), not a sfv file. If no filename is specified, it'll rescan the whole directory.
