OK here’s a solution until the next release:
1) Open the file assets/plugins/managermanager/functions/fields.inc.php
2) Find the content case near line 115.
3) Change the code from:
$output .= '$j("#sectionContentHeader, #sectionContentBody").hide();';
$output .= '$j("#ta").parent("div").parent("div").hide().prev("div").hide();';
The reality is that there really should be a single wrapper div with an ID around the content section to make it easier to get both pieces at once, but jQuery sure does make this nice and simple!
Someone please file a report for this in JIRA; currently down for maintenance and I don’t want to overlook this issue.
This is a 1.0.1 specific bug, so moving there.
