My client installed this plugin and is occasionally receiving the following errors:
Warning: DOMXPath::query() [domxpath.query]: Invalid or incomplete context in .../plugins/wordpress-seo/admin/linkdex/linkdex.php on line 365
(Error repeats three time, but targets lines 278 and 293)
Also, in an alternating fashion (so for each of the previous errors, this error directly follows):
Warning: Invalid argument supplied foreach() in .../plugins/wordpress-seo/admin/linkdex.php on line 367 (then line 280, and 301)
Typically I would dig in, but I'm buried in three other projects, so I want to see if this has been noted by anyone else.
Thanks for you help!
