Class 'ext_noop_trace' not found

I updated freepbx 2.8 to 2.9 beta

Now when I try to run ./install_amp or apply configurations changes on admin prints this error:

PHP Fatal error: Class ‘ext_noop_trace’ not found in /var/www/admin/modules/core/ on line 1984

It seems ext_noop_trace its not recognize in all

any help or advice is welcome

something went wrong in your update.

ext_noop_trace is defined in class.extensions.php which used to be in /var/www/html/admin and has been moved to /var/www/html/admin/libraries (or what ever your www path is)

You may want to take a closer look at your updated to see what went wrong and if appropriate, help us understand how this could have happened if it is a bug that we can prevent.
