My website is hosted on godaddy attempted to migrate from Joomla 3.6.5 to 3.8.2 using joomla upgrade. Failed to fix it I copied postupdate.php and ran after which backend got restored but I am only seeing this error on each menu tab:

Call to undefined method JApplicationAdministrator::isClient()

Checked my db as suggested by this forum and I have client_id column already. Any suggestions.

Check for this function https://github.com/joomla/joomla-cms/blob/3.8.2/libraries/src/Application/CMSApplication.php#L742-L754 in your libraries/src/Application/CMSApplication.php file. I would also add that you really need to be moving to the latest version. Joomla 3 as a whole has been unsupported by the project since September after 2 years of maintenance. You need to move to 3.10 and then to J4 as soon as practically possible.

Feel free to search the Joomla! Forum how similar issues have been resolved in the past, for example Fatal error: Call to undefined method JApplicationSite::isClient() after update to 3.8
