I saw this too.
Got past it by editing /smart-link-final/prli-config.php
Changed line 3 from:
define(‘PRLI_PLUGIN_NAME’,”Smart-link-final”);
to:
define(‘PRLI_PLUGIN_NAME’,”smart-link-final”);
and it activates cleanly.
I am not the author or affiliated with the author, so I have no idea what other things might break as a result of this change!
At your own risk amigo
best regards
