It seems that there are lots of posts about the [+summary+] placeholder;
after reading i found out the I have the "summary.extender.inc.php" installed but i still dont seem able to get the content of the variable; I am using Modx 1.0.2.
Is there a specific way of typing ? I have tried [+summary+] and [*summary*] with no luck.
Try [*introtext*],
or [+introtext+] if it’s in a Tpl chunk used by an add-on.
