I will give you my credentials in the next message.
WordPress, X and plug ins are all updated.
The credentials above do not seem to be working. If necessary please provide working credentials.
Please try clicking Edit Page on your top WordPress Admin bar > Once you are on your wordpress classic editor > Under the blue update button you will find Page Attributes > Page Templates > Make sure you have selected Blank No Container Header Footer.
