I use Twitter Tools to create WordPress posts from Tweets.
I am getting the following error, intermittently:
PHP Fatal error: Call to a member function do_blog_post_tweet() on a non-object in /home/XXXXX/public_html/wp-content/plugins/twitter-tools/twitter-tools.php on line 740
Is there any known cause of this error? I also use FeedWordPress (http://feedwordpress.radgeek.com) on the site. There seems to be frequent mention of this error when you Google the term, but few solutions.
The only "fix" I found was installing a plugin called XRDS-Simple (Provides framework for other plugins to advertise services via XRDS) but that only temporarily worked, the error is back today.
Really need to sort this out as the site is due to go live soon.
