I installed this code at the top of _main.php
require_once('magpierss/rss_fetch.inc'); // added gg
and it works fine for the default blog but the Summary and Linkblogs don't load. They show a blank white page in the browser. Not sure where to go from here???
Upon further study the problem was not related to the change in _main but rather to something I must have done in the startup configuration.
When I start the browser at the root level of the domain it runs the script at http://myurl.com/index.php
After that, when you change between blogs it uses the index.php at
http://myurl.com/b2evolution/blogs/index.php?blog=4
Anything blog displayed by http://myurl.com/b2evolution/blogs/index.php?blog=4 is blank - so what have I done???
