WordPress and Kalium Server Requirements

To use WordPress and Kalium we recommend your host supports:

We have tested it on Windows, Mac, and Linux. Below is a list of items you should ensure your host can comply with.

  • Check to ensure that your web host has the minimum requirements to run WordPress and themes.
  • Always make sure they are running the latest version of WordPress.
  • If necessary, you can download the latest release of WordPress from the official WordPress website.
  • Always create secure passwords FTP and Database.


Many issues you may run into such as; white screen, demo content fails when importing, empty page content, skin not being saved and other similar issues are all related to low PHP configuration limits. The solution is to increase the PHP limits. You can do this on your own (learn how), or contact your web host and ask them to increase those limits to a minimum as follows:

max_execution_time = 120
memory_limit = 128M
post_max_size = 64M
upload_max_filesize = 64M
max_input_time = 60
max_input_vars = 3000

Also consider upgrading your PHP version to the latest version, the newer the better.


How To Verify Your Current PHP Limits?

You can verify your PHP configuration limits on the Kalium theme by just going to your WordPress dashboard > Laborator > System Status.

You can also do that by installing the FastDev plugin and then going to WordPress dashboard > Fastdev > and choose PHP tab to compare your server info (see example). The first column (Local) refers to your installation value, and the second column (Master) refers to the limits of your host. The latter values are often lower if you have selected a cheaper hosting package.
