Valerie –
One of two things..
1) you are not to upload the zip file that I sent. You are to extract the zip file that I provided and only upload the wplms.zip file as a new theme.
2) If you are doing #2 and still having issues, that is a memory timeout issue and due to the memory settings of your hosting account.. This part is quite involved and I don’t expect you to worry about this issue. I will correct it for you.
Can you verify if you we were attempting upload the zip file that you downloaded or the wplms.zip file that is one of the files in the original zip?
