Hello.

Problem: I am going to the admin center, then to the packages, then to the place to download and install, and when I want to click on the option of upoading files from my computer, nothing happens. Nothing happens and I can't select files from my computer to upload.
Weird. Try uploading the file into your "Packages" directory, using FTP. Then, go to Admin>Packages to install it.
Never mind. After turning off the coputer and turning it on again, it was fixed and I can upload packages in a normal way. Thank you anyway. I will use it in case it happens again and restarting the computer won't help.
