Well, okay... here's what you should do.
First, make sure you edited SSI.php and set up the paths. You'll need to *at least* set the $full_yabbse_path variable.
Second, check the settings with the full URL to SSI.php:
http://www.blah.com/yabbse/SSI.php?function=welcomeIf that works, try the SSI via your shtml page...
http://www.blah.com/test.shtmlWhich should contain code that includes the same URL. (
http://www.blah.com/yabbse/SSI.php?function=welcome)
This will *probably* work if SSI works.
