Voicemail Transcription Issues after 5.4 Upgrade

[UCtech]

Have not been able to get transcribe working after upgrading from 5.3 to 5.4. Voicemail to email is still working but where the transcription normally is located instead just shows ${message_text}. Was working fine before the upgrade. Using Watson. Transcribe queue shows nothing. Have tested in shell that it is running using systemctl status email_queue as follows:
root@xxxxx:~# systemctl status transcribe_queue

For the upgrade I followed the steps in 5.3 to 5.4 here:

Version Upgrade — FusionPBX Docs documentation

docs.fusionpbx.com

All of that went well but not sure what the "Domains member feature" is or where the "application manager" is so I did nothing with that part of the upgrade. Could that be part of the problem?
How do I fix the "Failed to open stream: Permission denied"?
Thanks in advance!

Sorry didn't see the warning line was truncated. The full warning is:
Failed to open stream: Permission denied in /var/www/fusionpbx/resources/classes/auto_loader.php on line 208
auto_loader.php line 208 is:
$interface_result = file_put_contents(self::$interfaces_file, "<?php\n return " . $interfaces_array . ";\n");
