Error updating theme using Smart Update in Plesk

Unable to update theme with Plesk’s Smart Update. License code is entered in theme options. Smart update clones website for visual comparison. Since a few weeks I receive errors when updating different themes (like bridge/enfold): Unable to update theme ‘themename’, details: One of the common causes of this error is plugin or theme requiring a license to be updated. Log in to WordPress admin dashboard and try updating this plugin or theme there to discover more details about this issue.
Anyone else with this issue, or hopefully a solution
