You are seeing this message because archive that is temporary created inside Storage folder for processing export and import is missing.
Reasons for missing archive inside All-in-One WP Migration plugin Storage directory are:
- wrongly set file permissions for ‘storage’ and ‘ai1wm-backups’ folders
- a presence of antivirus software that scans for files and recongnize the temporary created ones in Storage directory as dangerous and deletes them
‘storage’ folder is required to be present inside All-in-One WP Migration plugin directory: ‘/wordpress/wp-content/plugins/all-in-one-wp-migration/’ and is used for storing temporary data that is created, read and deleted. ‘ai1wm-backups’ folder is requred inside ‘/wordpress/wp-content/’ directory and is used for keeping created backups. For the plugin to function properly, you may need to create these folders manually and grant them read/write/execute permission (0777).
In case the ‘storage’ and ‘ai1wm-backups’ folders are present and has correct permissions set, please check your antivirus program settings to see if it recognizes the temporary data inside Storage as a thread.
If you have done the above described checks and settings and you still encounter problems with your export or import process, please feel free to contact u as firstname.lastname@example.org.
