That shouldn’t matter - it should be the total number of sites that you have that hides or shows that button.
When you FTP’d these files up, did you delete the old ones first? I’ve seen this issue when files fail to over-write.
Also, please make sure you clear your browser cache to make sure you are seeing the latest updates.
If you still can’t see it, please do try deleting the old MSM files first and uploading the new from a new download; let’s make sure those 3 files are really the newest ones.
After all of this, if you are still experiencing the issue - let’s rule out a license issue before troubleshooting further. Please email sales with the license number for that MSM so we can make sure of how many licenses should be available. If you do end up doing needing to email us, please include this thread so that I have some background when looking this up.
Actually - even if you can get it to work, please do email sales with the MSM license number; you do not have one on your account so we need to verify it before offering further support. We can kill a few birds with one stone, so to speak, and get you moving forward with this site.
Thank you!
