The idea for this plug-in and the way it's been worked out, look great, but I think I may have run into a bug (?).
As soon as I activated the plug-in, this is what I got: "Warning: Illegal string offset 'feedslug' in /home/xxx/public_html/wp-content/plugins/wp-rss-multi-importer/inc/rss_feed.php on line 25"
The site where it's installed is http://scribent.com (test site -- nothing there, only rubbish).
My server is a dedicated CENTOS 6.3 x86_64 standard server running at Liquid Web.
Can you please help with this problem? (There's a considerable time difference between us, so I may not reply immediately -- sorry about that).
