No access to webgui after a plugin installation failed

Hi all,

i have no access anymore to the OMV 1.x webgui after a plugin installation crashed. I assume it's the virtualbox plugin although omv and the virtual machines are still running fine.
The error message i get when i try to login via the webgui is:

Failed to connect to socket: No such file or directory
Error #7001:
exception 'OMVException' with message 'Failed to connect to socket: No
such file or directory' in /usr/share/php/openmediavault/rpc.inc:135

#5 /var/www/openmediavault/rpc.php(32): OMVJsonRpcProxy->handle()
#6 {main}

I searched the forum and found that for troubleshooting the output from "omv-engined -f -d" is important to figure out the issue:
PHP Warning: require_once(/usr/share/phpvirtualbox/lib/config.php): failed to o pen stream: No such file or directory in /usr/share/openmediavault/engined/rpc/v irtualbox.inc on line 22
PHP Fatal error: require_once(): Failed opening required '/usr/share/phpvirtual box/lib/config.php' (include_path='.:/usr/share/php') in /usr/share/openmediavau lt/engined/rpc/virtualbox.inc on line 22

So if virtualbox is the issue is there any chance to fix it without reinstalling all the VMs?

Thanks in advance for your help.

Best Regards
