Ok, tried a complete new install. Everything on wp3.6
1- Created a backup on 'site a' (49.73mb total)
2- created new WP install 'site b'
3- Installed wp clone
4- tested by creating backup and restore... ALL OK!
5- inputted 'site a' backup URL
6- The following errors were reported
Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in /home/***/public_html/***/wp-content/plugins/wp-clone-by-wp-academy/lib/functions.php on line 245
The plugin encountered an error while cloning the database,the following error message was returned:
Error Message : MySQL server has gone away
My guess is this plugin, as it stands is only suitable for small sites with a small archive payload. The one click simplicity of not having to section the site into various backup options (db/uploads/files/etc)is also the drawback when the site becomes larger for memory limits to handle.
For a new site this is all sweet and lovely, but a maybe a problem waiting to happen as the site grows in size.
Not a criticism, but your comments as to how to avoid that problem are appreciated ...
