The “Maintenance Notice” will be displayed when the data file has not yet been created.
When the plugin is activated for the first time, the data file is usually created after a user visits your site. (Until then, it is marked as under maintenance.)
Also, when a plugin is updated, it will be temporarily under maintenance.
However, if “Maintenance Notice” is displayed all the time, the following may be the case:
-Server environment issues
If your server does not have the wirte permission to files, the plugin may not run.
See Notes on Installation for countermeasures.
There is a possibility that the aggregation program in the cron is not running properly.
In that case, deactivating and then activating the plugin may solve the problem.
Also, please make sure that you do not have “Do not run cron” in a file ‘wp-config.php.’
If the code “define(‘DISABLE_WP_CRON’, true);” is written in wp-config.php, cron will not run.
Either remove this code itself, or set ‘DISABLE_WP_CRON’ to “false.”
– Other considerations
If there are really few access to your site, or if you have a cache plugin installed, it may be slow to start accumulating data. Please clear the cache of all pages once and then wait another day.
*As for the “Heatmap Manager” screen, if you activate the plugin for the first time, you will be able to see the data from the day after the nightly aggregation is over.
*If the above does not solve your problem, it may be due to your site’s unique environment. Please read our Support section before contacting us.
