This error occured just recently after I run update.php: Error: Call to a member function get_access_callback() on boolean in views_plugin_display_page->execute_hook_menu() (line 96 of .../sites/all/modules/views/plugins/views_plugin_display_page.inc).
What could be wrong?
This worked well in views 7.x-3.21 but stopped working in 7.x-3.23.
Fixed

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Thanks #28 adrianolmedo, the manual script update described allowed to get my site backup.
I was also working on installing/activating Commerce module and its related modules/features. Initially I built a Commerce-WebForm form on my local host. Next step was to build it on the shared hosting site, then the errors appeared. Happy to get my hosted site backup and plan next steps.
