Here is the code:

the problem isn’t that it doesn’t show thumbs the problem is that it zooms into the selected thumb

oh sorry, tehbigwebtheory I am using newspress.

okay I got this sorted out out. I went on filezilla and changed the php. I checked if it transfered properly on my wp editor. It did. Problem is that is still is zoomed in!

I changed it it now I cant do anything, not even change it back. It tells me even at my dashboard that it’s unable to connect to tehbigwebtheory. OMG HELP!
