[Plugin: BackUpWordPress] shell_exec() issue

Thanks for reporting your issue.

Do you see the following warning on the manage backups page?

? shell_exec is disabled which means we have to use the slower PHP fallbacks, you could try contacting your host and asking them to enable it.

I’m working on a fix for this issue, in the meantime adding the following to your wp-config.php file should fix the issue.

define( ‘HMBKP_MYSQLDUMP_PATH’, false );
define( ‘HMBKP_ZIP_PATH’, false );

I’m having similar issues. Although safe_mode ‘seems’ to be off (phpinfo says that) i’m getting:

Warning: shell_exec(): Cannot execute using backquotes in Safe Mode in /[…]/wp-content/plugins/backupwordpress/functions/backup.files.functions.php on line 69

my phpinfo:
https://dl.dropbox.com/u/1978324/backupwordpress/index.html

uh: btw: if i

define( 'HMBKP_MYSQLDUMP_PATH', false );
define( 'HMBKP_ZIP_PATH', false );

the errors are gone, but i cannot make any backups. .htaccess file is created but no sql backup.

Do you have access to your server error log?

It looks like your server may be running in safe_mode even though php_info reports it isn’t.

Uh, oh, all sorts of weird things. you should know that i’m testing on a synology server right now, where everything seems to be fucked up – related to web-dev.. so php was logging to syslog, which is normally not accessible. so i had to edit the php.ini a little bit. i found out that they used a windows default ini, which was causing quite some trouble. now i have access to the logfile, but there’s nothing in there. simple errors get logged though. anyway: thanks for trying to help me, but this gets way too much for you, since it is way too specific. i wrote my own cronjob for backing up my database with rotation now. the files get backupped by a synolgy cron script, so i’m fine with that too.

I’m having the same issue. It began just after an automatic upgrade of WordPress:

I made the additions noted above to wp_config.php, but still have the warnings. And it prevents me from accessing the WP Admin Dashboard:

Warning: shell_exec() [function.shell-exec]: Unable to execute ‘hash mysqldump 2>&1’ in E:\Sites\Single1\battenkillbooks\webroot\index\wp-content\plugins\backupwordpress\hm-backup\hm-backup.php on line 712

Site is live and loads, but has two warnings at the top:

Warning: shell_exec() [function.shell-exec]: Unable to execute ‘hash mysqldump 2>&1’ in E:\Sites\Single1\battenkillbooks\webroot\index\wp-content\plugins\backupwordpress\hm-backup\hm-backup.php on line 712

Is there a simple way to deactivate BackupWordPress? Or do I have to do a complete manual re-install of WP?
