Supported Environments

QA Analytics supports an environment following:

  • PHP version: 5.6 or higher
  • WordPress version: 5.6 or higher
  • Recommended server specs: 4GB or more memory; SSD is preferred for hard disk.
  • PHP memory_limit: recommended 1GB or higher
  • PHP max_execution_time: recommended 240 seconds or longer

Requires file write permission

Some servers have file write restrictions for security reasons, etc., and may require a password when installing plugins.
In that case, QA Analytics will not be able to write data and no data will be recorded.


Set “write” permissions under the QA Analytics data directory, (ordinarily) “wp-content/qa-heatmap-analytics-data/”, to work properly.

Take note of PHP settings.

Considering the specifications of QA analytics, it is susceptible to the effects of “memory_limit” and “max_execution_time”.
Please adjust the server environment as needed.
Regarding settings of “php.ini”, inquire with your hosting provider.
