unable to modify the settings

Hello ! When I try to modify the option “Regex Exclude Files”, I get a reply Not Implemented POST not supported for current URL. So, I tried using phpmyadmin ; I tried to modify the table wp_options , the key xcloner_regex_exclude . I tried to modify the value. From (wp-content\/updraft|wp-content\/uploads\/wp_all_backup|wp-content\/ai1wm-backups|wp-content\/plugins\/akeebabackupwp\/app\/backups)(. ).(. )$(?<!config|php|html|htaccess|htm) (. ).(svn|git)(. )$ wp-content\/cache(. )$ (. )error_log$ xcloner-[0-9a-zA-Z]{5}$ to (wp-content\/updraft|wp-content\/uploads\/wp_all_backup|wp-content\/ai1wm-backups|wp-content\/plugins\/akeebabackupwp\/app\/backups)(. ).(. )$(?<!config|php|html|htaccess |htpasswd |htm) (. ).(svn|git)(. )$ wp-content\/cache(. )$ (. )error_log$ xcloner-[0-9a-zA-Z]{5}$ but I get a reply Error in processing request Error code: 501 Error text: error (rejected) It seems that the connection to server has been lost. Please check your network connectivity and server status. For information, the plugin is well working ; the backup are correctly performed. Hello, That may be due to a hosting security protection, I suggest you to contact your hosting company and ask about. Regards hello, thank you for your support, but this is not the case, as I can change other parameter from xclone. The table wp_options is writable. But not this parameter. So the problem is still there… Nevertheless, I would recommend to exclude by default htaccess AND htpasswd Cheers
