I have tried installing the plg_system_t3.v2.7.0.zip by uploading a package and by using the upload by folder.
By package error: > Error
There was an error uploading this file to the server.
Maximum PHP file upload size is too small: This is set in php.ini in both upload_max_filesize and post_max_size settings of your PHP settings (located in php.ini and/or .htaccess file).
Unable to find install package
By folder: > Warning
JInstaller: :Install: Can’t find XML setup file.
The Joomla package cannot be installed through the Extension Manager. Please use the Joomla! Update component to update Joomla.

Path does not have a valid package.
Any other ways to install it?
Thank you.
