I am not certain how to read these codes. Perhaps above my help. Does anyone know how to correct this error? Or should I simply re-install and try again? Thank you very much.

And does someone have a recommendation for a theme I can use/purchase that is very stable, and provides for color selections and movement, and typing over text over pictures along with the posting of videos? I am assuming I will need to start over.
Enjoy a nice weekend.
