These are the minimum requirements to run Toolset plugins:
- WordPress 3.4–4.7.1 (it’s always a good idea to run the latest and greatest version of WordPress).
- PHP 5.3 and above (including PHP 7).
- MySQL 5.6 and above.
- 128MB RAM (see WP memory settings). Keep in mind that the required memory for your site depends on your content, theme and all plugins.
Please note that while Toolset works with PHP 5.2.4+ and MySQL 5.0+, they reached the official End Of Life, and are not recommended for security and performance reasons.
How to check the PHP version
You can check the version of PHP that’s running on your server using a WordPress plugin (such as WordPress phpinfo()) or by uploading a tiny test file to your site.
To create your own php_info.php file, do this:
- Create a new file called php_info.php. The file should contain just a single line:
- Use an FTP program to upload it to your site’s root folder.
You should see something like this:
On the first line, you will see which version of PHP you are running. If you are using PHP version earlier than 5.3, Toolset will have problems running on your site. Your best option is to email your hosting company and ask them to upgrade you to PHP version 5.6 or later. Currently, PHP 5.6 is the most stable version of PHP and PHP 7 is the fastest version (but some themes and WordPress plugins are not yet compatible with it).
Troubleshooting server-related issues
If you run into any server-related issues, such as the so-called “White screen of death” or 500 Server Errors, there could be many different causes for this.
There are some basic things that you can do yourself:
- Make sure that your server follows the recommended (or at least the minimum) server requirements. If it does not, contact your hosting provider and ask them for a setup that will match the requirements.
- Increase the memory-limit option in WordPress. Often, issues arise from low memory allocation. You can try to increase the allocated memory by editing your site’s wp-config.php file. For more information on how to do this, please read the official WordPress documentation on increasing memory allocated to PHP.
- If you get a 500 Server Error when using Views, increasing the max_input_vars PHP setting might help. You can find detailed information about this in our FAQ.
