I’ve recently started getting the following warning:
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘feed_links_extra’ was given in /home/rggwebd1/public_html/tgc/news/wp-includes/plugin.php on line 339
I thought it was because I edited the search bar (just removed the label), but upon seeing the ‘feed_links_extra’ it obviously seems to be a problem with the RSS feed links.
These had not been working since I installed WP, but this is the first time that error has come up.
What should I do? Is there an option in the dashboard to “restore” the system?
