Problem with mobile api after migration 10.4.4>11.5.30

[Paul Tog]

Hello,

yesterday i completed a full migration of my server from version 10.4.4 to 11.5.30 using Migration Manager.
The old server had the mobile api connector installed and working just fine. I had my Android phone connected and monitored the stats.
Now on the new server, although the referring page shows correctly, the folder /usr/local/psa/var/modules/plesk-mobile doesn't exist. Thus, the mobile application cannot connect to the new server.

If i run

/usr/local/psa/bin/extension --uninstall plesk-mobile

i get the response Module plesk-mobile is not installed.

If u run

/usr/local/psa/bin/extension --install plesk-mobile

i get the response Unable to open source file. File not exists.

What can i do to resolve this? i really need to keep an eye on the cpu & ram as it is a new machine and problems may arise.

Thank you in advance

Regards

Paul
