500 Internal Server Error when saving template settings

[Joomla 3.0.3; CB 1.9; IIS 7 on 2008]

Hello. When clicking SAVE while in template settings at admin panel, I'm getting the 500 Internal Server error.

It doesn't happen when clicking SAVE&CLOSE.

Memory = 64M; TMP and LOGS folders are fully accessible to all machine users.

PHP Notice: Undefined property: TemplatesTableStyle::$checked_out in C:\Inetpub\vhosts\MyJoomlaSite\libraries\legacy\model\form.php on line 99

This is a PHP error saying that the checked_out variable is undeclared at the time that form.php is calling for it.

I looked into that php page and unfortunately I could not find a glaring issue other than that it was never declared :blush:

Please help.

Hello,
I have the same Problem, if i Update a Profile.

Saving a Joomla template or a CB template? Am not able to confirm with either, but am on Apache and not IIS. Are you both on IIS? Also note what you provided is just a Notice and would not cause a 500 error, please enable debug mode and maximum error reporting in Joomla global configuration (both are important) to expose errors then re-test and see if there are any on-screen errors.
