Williams, 54, recently took a break from her show, claiming health issues were the reason.
The star has been dealing with a shoulder fracture and has raised eyebrows with odd behavior.
But although "Wendy was supposed to return to her show on Monday, January 7, she is taking another week off," a source told RadarOnline.com.
"Her staffers were notified late on Friday night and will now have to cancel all of their bookings and rearrange future tapings to accommodate Wendy being gone."
While the show announced on Instagram on Friday, January 4, that Williams would be back on her show on Monday, the 7th, the post was later removed.
The star's apparent meltdown came as her husband Kevin Hunter was accused of getting his secret mistress Sharina Hudson pregnant.
Both Williams and Hunter have vehemently denied those reports.
Hunter has been charged with having a 10-year affair with Hudson.
RadarOnline.com exclusively discovered that Hunter's alleged love nest with the alleged other woman has gone up for sale.
Williams announced in late December that she had fractured her shoulder — but an insider claimed to RadarOnline.com that the daytime TV host has something much more serious going on with her health.
"Something bad is going on with Wendy," the source told RadarOnline.com exclusively, adding that the December 17 episode was cancelled at the last minute and replaced with a rerun.
The insider insisted Williams has been exhibiting strange behavior "for weeks."
Or even months! She burped and coughed during an earlier health scare in March 2018.
She's had other unexpected absences from TV as the host has battled Grave's disease.
