Increase Memory

Some hosting providers limit PHPs ability to use additional memory or cap the limit very small. This issue tends to be more common onlow-end budget hosts. The options below can help you increase PHP memory.

Option 1 1. If the memory error occurs when creating a package then edit your wp-config.php file and add this:
define('WP_MEMORY_LIMIT', '500M');2. Edit your .htaccess file in your WordPress root
<IfModule mod_php5.c>
php_value memory_limit 500M
</IfModule>3.Edit the php.ini and set:memory_limit = 500MB

Option 3Contact your host with the memory error and have them increase PHP memory for you.

Validating Memory
After updating any of the options above be sure to make check that the setting are updated. You can do this by going to: Duplicator/Pro >Tools > General > Server Settings > PHP Section > “Memory Limit” and make surethe value matches the value in one of the above options.On some system the web server will have to be restarted.

Its recommend to set the value 50% above the memory setting before any updates were made. For example if your memory setting was at 250MB before the memory errorthen the new settings would be 375-400MB. If that doesn’t work try 100% of the allocated warning which would be 500MB.

Package Builds

When building a package try to use the following settings if available on your host:

• Duplicator: Settings > Packages > SQL Script > Mysqldump
• Duplicator Pro:
  • Settings > Packages-Basic > SQL Script > Mysqldump
  • Settings > Packages-Basic > Archive Engine > Enable “DupArchive” or “ShellZip”
    These engine options consume much less memory than ZipArchive
  • Settings > Packages-Basic > Server Throttle >
    This prevent resource complaints on budget hosts. The higher the value the slower the backup

Running Installer

If running into memory issues on the installer, Pro users you can also use the ‘Manual SQL Execution’option by followingthese steps:

1. Have your host or server administrator run the database.sql file for you. In some cases you may be able to use phpmyAdmin if the memoryoptions to run it are different than how your web server is setup.
2. After the database has been installed go to step 1 of the installer and choose ‘Manual SQL Execution’ from the Action drop-down.
3. Continue to finish out the installer as you normally would.

When creating or installing a package a notice about disk space issues is logged.

Overview
If you’re not sure about your Disk Quota contact your host. Some hosts will advertise that you get “unlimited space”, however the truth is a quota isplaced on every accountaccording the the Terms and Conditions of the account. Many hosting control panels or cPanel accounts give you an unlimited number of domains you can setup.With each domain they create a new directory and hosting control panels or cPanel silo for that domain which usually has a quota on how much space you can allocate to that directorysee the link above.

Most web hosts control panels will have a progress bar on the main dashboard that shows how much space you have for the specified domain. If you’re not using a cPanel setupask your host where you can find out your disk quota. So in short try to get a real answer from your host and if they still give you a canned response then try to uploada file which should be 5 times the size of your ‘Pre-Scanned’ site size. So if the pre-scan shows 50MB then try to upload a file that 250MB add see if it allows the file to upload.If it does not then you definitely have a disk quota issue.
