I have a problem, when I go to the tap plugin management. not show anything.
in the directory plugins I have installed 3 directory plugins. but I cant install another plugin.

could help me, Please.

Cacti 0.8.8h is seriously old and doesn't support newer PHP versions like 7. If you are going to use a new PHP, then you are going to need to use the latest Cacti also.
