Why does my Resume Upgrade Always Fail?
After upgrading to Popup Maker v1.4+, and running the DB upgrade you are getting an error Message on admin pages:
"Popup Maker needs to complete a database upgrade that was previously started, click here to resume the upgrade."
When you try to resume the upgrade it shows:
"Upgrade failed, please try again.".
The Underlying Issue
Generally the update has finished but never cleared the stored value that is used to resume updates.
- Add delete_option( 'pum_doing_upgrade' ); to your themes functions.php file.
- Refresh your browser a few times until it dissapears.
- Edit your functions.php file and remove that line.
