# Fatal error – cannot activate

 * Updated WP Staging to version 2.4.4 earlier today. The plugin was already activated
   at that time. After updating, experienced problems with editing posts/pages. 
   Could not switch from visual editor to text view, and could not insert or update
   links in visual editor. Editing problems went away when WP Staging was deactivated.
   Now when trying to activate WP Staging again, activation fails with this error
   message: “Plugin could not be activated because it triggered a fatal error. Fatal
   error: Using $this when not in object context in [file_path]/plugins/wp-staging/
   install.php on line 29.”
 * Site is not yet updated to WordPress 5.0 pending testing.

 * Hello [@sscott201](https://wordpress.org/support/users/sscott201/),
 * can you send me a mail to support [at] wp-staging.com with system info log from
   wp staging > tools > system info?
 * I’ve reverted wp staging to the previous version. Can you reinstall it with version
   2.4.3 and let me know if this resolves the issue?
