I was having difficulty with a Joomla! site and decided to move it to another server for testing. The Akeeba backup I had would not fully extract for some reason (a large backup file included in the backup), so I downloaded all 30k+ files manually via FTP and uploaded them directly to the new server. I, also, backed up the database via phpMyAdmin and restored it to the new server.
When I access the front-end of the website, everything loads and works as it should. However, when I access the
administrator, I receive the following message after logging in:
Failed to start the session because headers have already been sent by "/home/userfolder/public_html/plugins/system/statusindicator/statusindicator.php" at line 169.
I cannot access any
administrator pages after logging in. I've tried installing the Joomla! core over the top and that did not fix it. I've, also, tried resetting the db credentials and that did not fix it.
What could be the issue causing this error?
