My problem happen after installation. When I try to open the app I have an error:
Fatal error: Call to undefined function Akeeba\Engine\Driver\mysql_close() in /X/wp-content/plugins/akeebabackupwp-4.1.0.rc5_/app/Solo/engine/Driver/Mysql.php on line 143
I fixed it replacing mysql_close by mysqli_close
But after I have another problem:
Fatal error: Using $this when not in object context in /X/wp-content/plugins/akeebabackupwp-4.1.0.rc5_/helpers/templates/wp/php/head.php on line 34
