All of a sudden I receive an error on my BLOG, in the sidebar right above three RSS widgets I use to display some external stuff. The feeds are displaying fine, but above them I get this:
Warning: array_map() [function.array-map]: The first argument, 'map_attrs', should be either NULL or a valid callback in /home/ccozzi/domains/carlitoergosum.nl/public_html/wp-includes/rss.php on line 175
After a reload it is fine again. It seems to correlate with the use of PressThis to post something, but I haven't been able to reproduce it yet.
Thanks for any pointers.
