Removed (renamed) my existing userdata -> addon_data -> service.webgrabplus folder then updated addon and tried out latest release and can confirm everything working well and as expected.
I understand better changes you have incoperated in service.webgrabplus-*.0.92 release for LibreELEC.
Really enjoying simplicty of webgrab++ set-up now with LibreELEC running as a service, where all typical user needs to do is access userdata -> addon_data-> service.webgrabplus -> siteini.pack -> [Country(s) of user Channel (to obtain EPG information) Interest]
Enter and then select channels strings required from user selected .channels.xml (with favourite text editor)
add text strings to userdata -> addon_data -> service.webgrabplus -> WebGrab++.config.xml (with favourite text editor)
Save changes in WebGrab++.config.xml
Then run via ssh, webgrabplus.start (which has benefit of providing running job information on the ssh'd screen as the webgrabplus job is being run on the LibreELEC device )
