# [Plugin: WP-DBManager] PHP fatal error – memory size exhausted

 * The plugin is working fine, but it is not emailing the DB backup to my set email.
 * Checking why, I found a ‘fatal error’ in my logs:
 * Fatal error: Allowed memory size of 94371840 bytes exhausted (tried to allocate
   22848477 bytes) in /home/user/domain.com/wp-content/plugins/wp-dbmanager/database-
   manage.php on line 86
 * **Line 86:** $file_data = chunk_split(base64_encode($file_data));
 * Is there anything in the settings I need to change?
 * Thank you for your help.

 * Thanks, I increased the PHP Memory to 64MB as described in the codex.
 * The error message is gone now, but WP-DNManager still does not send the backup
   file as an email.
 * Manage Backup Database –> Select –> Email
 * Returns empty dashboard screen

 * I would recommend 128 or 256mb, also do a stopwatch to time if it takes more 
   than 30s to execute the script.

 * Hi Lester,
    I changed to 256mb and my loading time of the website sped up incredibility
   which is great. I didn’t know this little tweak.
 * Unfortunately I still get the error:
 * Fatal error: Allowed memory size of 94371840 bytes exhausted (tried to allocate
   22781371 bytes) in /home/user/domain.com/wp-content/plugins/wp-dbmanager/database-
   manage.php on line 86
 * 3 to 4 sec to display the error message

 * Wow looks like your site is using a lot of plugins? Try 512?

 * Thanks for your replies. Unfortunately, it still doesn’t work..
 * May it be something else?

 * Could you try disable all plugins except WP-DBManager to see if it works? Because
   it is unlikely your site takes up so much memory

 * I found the culprit:
 * The settings need to be set to file being zipped. Otherwise it’s possibly too
   large for emailing.
 * Thanks for this great plugin and prompt support:)
