It is possible that the heatmap data has not been correctly aggregated.
Most likely, the “max_execution_time” set in ‘php.ini’ is too short and the aggregation process is not completed.
Please set “max_execution_time” to at least 240 seconds.
Each rental server has its own settings, so please see and contact your rental server for details.
If there are any other problems with the server settings, the aggregation may not be completed properly.
For details, please see “Notes on Installation“.
