QA Heatmap Analytics takes a little time during the initial installation process to build the Table in the DB and register search engines, etc.

Some rental servers are set to have a short timeout for the connection to the administration screen, so you may get a 504 error and timeout.

In this case, if you reload the page, you will find that the plugin has already been activated in most cases. If it has been activated, you can use it as is.

If it is still disabled, please try to enable it again.

If you still get 504 errors and timeouts, you can try extending the timeout period in php.ini.

Edit the following items in /etc/php.ini.

max_execution_time = 300

The configuration method varies depending on the rental server. Please follow the manual of the rental server for details.
