Same exact error:
Fatal error: Call to a member function get_page_permastruct() on a non-object in /home/**********/public_html/wp-includes/link-template.php on line 271
The jetpack version seemed to update ok and I activated the widget visibility module – all seemed good. Then I tried to activate the new “wordpress.com connect” module and that killed everything. I get a white screen on the front of site and in back-end. deactivating jetpack brings everything back, but I cannot re-enable and use all the stuff I previously enabled and ignore the one that kills it as it goes straight to the white screen.
