System Requirements for using WPL and Add-ons
Posted by Howard R. on 13 September 2022 07:35 AM

You can have the option to use High Performance Realtyna Hosting for your project which is super optimised for Realtyna products or use your own web hosting provider.

Please note that for some of our complex products and high-load processes like MLS / RESO Web API / VOW functions, you should avoid shared web-hosting. 

Below is a list of systems that work with WPL and add-ons:

  • Linux Host
  • Apache Server 2.x.x or higher (or other standard web servers such as Nginx or Light Speed etc.)
  • PHP 5.4.x or higher
  • MySQL 5.6.x or higher (APS Add-on requires MySQL 5.7.x and higher) Or MariaDB 10.1 and higher
  • MySQL STRICT_TRANS_TABLES must be off.
  • WordPress 4.0.0 or higher
  • CURL Library
  • Allow_url_fopen set to ON in php.ini
  • GD Library, also "freetype" package should be installed and configured with PHP
  • Safe mode should be off.
  • Magic quote should be off
  • Memory limit should be set to 512 MB for WPL installation (Min. 128 MB)
  • PHP "ZipArchive" extension * must be installed for updating the PRO version of WPL and its add-ons.
  • PHP "Multibyte String" extension ** must be installed for using pdf generator feature.
  • Memory limit should be set 256 MB (Min)
  • System wide Cron Jobs are required for some addons like Importer, MLS, etc.
  • You need a powerful web-hosting or preferably a VPS or dedicated server for MLS Integration or Listhub integration
  • iconv PHP Extension should be installed for MLS integration.
  • Some RETS feeds may needs unusual port number (port 6103) to be opened in your web-hosting's firewall. Generally, Firewall should allow the connection to the MLS server.
  • In terms of hosting storage, for MLS integration or Listhub integration, by average 5 MB space (depending on MLS provider) per listing is required. It may raise to 15MB per listing for RESO WebAPI integrations.
  • For MLS integration/Listhub integration, the hosting should not have any limitation in inode (file counter).
  • For Soap based MLS providers, PHP-SOAP extension should be enabled on the server.

* compile php with --enable-zip option at the server side
** compile php with --enable-mbstring option at the server side

To run any kind of sophisticated web based software such as WPL, your server needs to meet the requirements listed above.


  • WordPress debug mode should be off.
  • cPanel (recommended but not necessary)
  • For integrations, try to have VPS, since over 90% of the cases, could not run on Shared hosting plans due to hosting limitations. 
  • Almost all Wordpress Managed hosting plans are not supported. Please check with support team for further details.
