Just to add: I now practice using WPO’s image optimizer before I publish my post and I have done away with using the same dev’s MetaSlider as a related post deal … Now placing my own custom HTML widgets under content to achieve better click-through. Since that time, no errors of any kind, including a “recoverable fatal error” that kept occurring naming my theme. Kudos and more thanks!
