We have noticed that you have provided incorrect WP-Admin access (https://prnt.sc/2fkL5IlkU-zd).
We kindly suggest that you go to Appearance > Widgets and check the content of the widget areas to ensure that there is no empty static block widget added.
We thank you for your cooperation and remain at your disposal for any further assistance.
