RSS import not working

here is what I would do…put in the url into the address bar of the browser…if it gives you a timeout, then the problem is likely with your server…if it says success, then the plugin is working as it should. (I just did that for your site and, while it took awhile, I got a success with this
http://www.buzzbazar.eu?rssmi_feedID=1, 2,3,4,5,6,7,8,9,10,11, 12,13,1

…thus the problem is your server is likely very slow and it’s giving a timeout to your cron (which is likely set for something faster)

try putting the feeds into categories and using the category url, not the feed url in the querystring…or set up a smaller crons and schedule them for different time, like;

http://www.buzzbazar.eu?rssmi_feedID=1, 2,3,4,5

http://www.buzzbazar.eu?rssmi_feedID=6,7,8,9,10

http://www.buzzbazar.eu?rssmi_feedID=11, 12,13
