Unable to upload MagicSpam extension in Plesk Onyx 17.8.11

[magicspam]

Dear MagicSpam Customers,

In Plesk Onyx 17.8.11, the Upload option is not available unless you add the following lines to the panel.ini file:

-----------------

[ext-catalog]

extensionUpload = true

----------------

Please see:

https://docs.plesk.com/en-US/onyx/admin ... 28/#o78343

for more information.

Please note that if panel.ini file does not exist and you have to create it, make sure to change permissions with

chmod 644 panel.ini

otherwise it will have no effect.
