Im trying to update from 5.6.0.2 to 5.6.2.1 but when i hit the update button this pops up everytime, and i have to run my backup to get the site running again.


"An unexpected error occurred.

Unable to get permission key for write"

if ($view->supportsPageCache($_pageBlocks, $this->controller)) {
                  $pageContent = $view->getFromPageCache();
                  if ($pageContent != false) {
                     Events::fire('on_before_render', $this);
                     if (defined('APP_CHARSET')) {
                        header("Content-Type: text/html; charset=" . APP_CHARSET);
                     }
                     print($pageContent);
                     Events::fire('on_render_complete', $this);
                     if (ob_get_level() == OB_INITIAL_LEVEL) {
                        require(DIR_BASE_CORE . '/startup/shutdown.php');
                        exit;

Hello,
Could you post this to the bugtracker and include your environment information?

http://www.concrete5.org/developers/bugs...

I'm curious of a couple things.

1. Is Full Page Caching enabled? (try with it disabled)
2. Are you upgrading as the admin user or another user with Administrator privileges? (try it as admin)

Best Wishes,
Mike
