I get the above errors when trying to load my dashboard.
I enabled the debug mode because my dashboard was looking a bit weird. It doesn’t display the top admin bar and nothing happens when I click on screen options.

I tried googling all these error codes but I couldn’t understand the solutions.

I hope someone can assist me here. Thanks in advance.
