I just migrated my website from InMotion to Site Ground using a plug in called UpDraftPlus.
It appears all of my calendar events migrated over – but the calendar view page is no longer working.
Thanks for contacting us though I am sorry to hear you are experiencing difficulties.
As a first step, can you login to your (new) site and visit the Settings → Permalinks screen: you don’t need to change anything, though, as just visiting this screen causes WordPress to ‘refresh’ its list of rewrite rules which are used to ensure the correct pages can be found and loaded.
I’ll go ahead and close this topic but if we can help with anything else please don’t hesitate to create a new topic and one of the team will be only too happy to help.
