 With the update to version 4.9, the site footers suddenly became 2 inches
 tall from what was 1/2 inch. Upon adjustment to customizer in control
 panel, footer returns to normal. Next day, site footer is gone. 4.9 update
 is gone too and wants to me re-update again. Re-update to 4.9, footer
 returns but is again giant size. Upload to site backup for 4.9 removal,
 sites return to normal. Next day, footer is gone, update to 4.9 is gone
 again, wants me to update to 4.9. Update to 4.9 third time, footer return
 to giant size. Next day, footer gone. 4.9 update gone again too. I can
 only wonder what happening at night to my websites. Using the same theme
 on multiple sites, each site is experiencing the same identical issue
 described above.

 There is also a bug issue with update 4.9 disabling the control panel
 customizer. The site cannot be customized or repaired due to this
 disabling by the 4.9 update. The theme's (Onetone theme) customizer is
 also disabled by the WP 4.9 update thereby rendering the sites uneditable.

 Anyone have any ideas or info on this bug yet? Is anyone else reporting
 such errors? Is there a solution in effect?
