I recently upgraded my ExpressionEngine installation from version 2.1.1 to version 2.1.3 build 20101220. The installation worked fine but I found that the excellent extension from VayaCode, QuickSave, didn’t put the preview or close buttons below the entry’s fields.
Luckily the fix was pretty simple – all I had to do was re-add the appropriate code to the /system/expressionengine/config/hooks.php file. Here’s the code:
Fixing the QuickSave EE2 extension:
$hook['post_controller_constructor'] = array( 'class' => 'Quicksave_ext', 'function' => 'cp_tweaks', 'filename' => 'ext.quicksave.php', 'filepath' => 'third_party/quicksave' );
After making this small change your QuickSave extension’s Save, Save and Preview & Save and Close buttons will be back where they’re supposed to be.
