Hi @phihung91nd,
I hope you are doing well.
Does this error disappear if you deactivate Post SMTP?
Thanks and regards,

Hi @smakazmi15 @haseeb0001 ,
This issue disappears when deactivating Post SMTP. It’s due to the function is_child_theme() called in the plugin. I think it’s not called at the right time. I have to use another smtp plugin.
