Urgent Issues after failed upgrade 8.2.1/back up 8.1
Also lost is the back ground image for the log in page. In the dashboard it is showing that it is set, but on the page itself it is not.
According to my Cpanel, I have successfully reinstalled the backup of 8.1, but checking my environment in the dashboard it is still showing 8.2.1
Would appreciate some help since I can not manage my sites members with this problem. I am not sure what other issues there may be yet to discover. Thank you.
When you restored your backups, were you restoring the files and database?
Have you cleared your concrete5 cache?
If clearing your cache doesn't resolve the issue and the current environment is still 8.2.1, then it might be that the backup/restore was not full (database and files) or didn't complete properly.
Also confused about why the background image for the log in page does not appear. I get the gray brick wall, but from the dashboard it shows my image is selected.
if it's showing something like
<?php return [ 'core' => 'concrete5-8.2.1', ];
then it is the problem.
if version 8.1 that you had was also an update then that file should contain
<?php return [ 'core' => 'concrete5-8.1.0', ];
otherwise if version 8.1 was a first install, that file should be empty
