I have installed Spigot 1.8.7 along with several plugins and
everything was working fine. However when I tried to add new plugins
today they seemed to download and install on the server (according to
the little green info box,) but are not showing up in Files or in the
game. 
I tried using a different web browser+android chrome browser too as was suggested in another thread but that didn't work either. 
Any solutions 
Thanks in advance.
Are you sure you used the appropriate plugin version?
Is there anything in the log when you start your server that says something about these plugins? (any error messages)
On Aternos there's a plugin limit, so you can only have 15 plugins at the same time. Maybe you installed too many..
Plugins should only be installed while the server is offline. Your plugins may not show up while your server is starting or online.
I have 12 plugins... when i install any other, its only say in green box Downloaded and installed, then i press X (close window) and wait for page refresh... But i dont see plugin in Files, its happened more times to me, server reinstall helped, but i cant reinstall now, because i have skyblock and i dont want to loose anything in it
