I saw for the hreflang Tags to appear on the sourcecode, you need to add following line to the concrete.php in the config folder:
'multilingual' => [ 'set_alternate_hreflang' => true, ]
but i don't see any change in the sourcecode. do i need to add it somewhere else too?
thanks in advance
sorry for not providing the information from the beginning:
If this file does not exist, you can create it with the following content:
<?php return [ 'sites' => [ 'default' => [ 'multilingual' => [ 'set_alternate_hreflang' => true, ], ], ], ];
Thanks a lot!
