Hi, @saguaros There is error message when I try install T4 System Plugin. The server returned a "500 - Whoops, looks like something went wrong."
How to fix it?
HI jakartaonlinemedia
Which Joomla version are you using? I can't replicate this issue at my end.
You can share the URL + super admin account so I can check.
Finally I installed it not by uploading to joomla backend, but by uploading via Cpanel. It work. Thanks.
