   “all-in-one-wp-
   migration-file-extension” plugin.
 * The latest version of the plugin (7.7.1) has an issue with the

 * it’s important to note that the “all-in-one-wp-migration-file-extension” plugin
   has been deprecated for more than two years. This means that it’s no longer recommended
   to use it as it may cause compatibility issues with other plugins, including 
   the latest version of the All-in-One WP Migration plugin.
 * Therefore, I would recommend that you deactivate the “all-in-one-wp-migration-
   file-extension” plugin and rely solely on the latest version of the All-in-One
   WP Migration plugin. This should help resolve the critical error that you’re 
   experiencing.

 * Ok, got it. I was just to lazy to figure out how to increase the memory limit
   for one hoster. 🙂
   Solved.

 * Hello, changes in php.ini or in .htaccess or wp-config.php do not solve the 300MB
   limitation in AIO-WP-Migration.
   The previous limit via AIO-WP-Migration-file-
   extension to 512 MB, was VERY significant.Damage
