Changing upload limit for WP All-in-One Migration
My server is stuck with file uploads stuck at 50MB or 100MB, but this two lines of codes in your .htaccess sorts it
php_value upload_max_filesize 512M php_value post_max_size 512M php_value max_execution_time 300 php_value max_input_time 300
That should sort ya – go back to WP All-in-One Migration Import and refresh.
However, if it doesn’t work, I would recommend this plugin – Big Uploads – and it should do increase your limit.
