datitisev I reinstalled because i could messed up with something and now with the same extend here
Kayo i get only one error on phperror log
[23-Jul-2019 15:08:23 UTC] PHP Parse error: syntax error, unexpected ']', expecting ',' or ')' in C:\MAMP\htdocs\extend.php on line 20
probably i'm simply sending this command to nowhere or using wrong command. going deeper on documentation from mediaembed is write there that i can make my own bundle by an existing bundle, i will try this.
// Use the Forum bundle's configurator
$configurator = s9e\TextFormatter\Configurator\Bundles\Forum::getConfigurator();
// Customize it to your need
$configurator->HTMLElements->allowElement('b');
$configurator->HTMLElements->allowElement('i');
$configurator->HTMLElements->allowElement('u');
// Save it back as your own
$configurator->saveBundle('MyBundle', '/tmp/MyBundle.php');
If i'm doing something stupid i'm sorry too, i really don't get very well these extenders.
