<h4><i>{{WARNING_ICON}}</i>Saving Dashboard Failed</h4>

<p>
Your dashboard couldn't be stored (error: "<?= $this->exceptionMessage; ?>"). This could have one or more
of the following reasons:
</p>
<ul>
<li>You don't have permissions to write to the dashboard file</li>
<li>Something went wrong while writing the file</li>
<li>There's an application error preventing you from persisting the configuration</li>
</ul>
</div>
<p>
Details can be seen in your application log (if you don't have access to this file, call your administrator in this case).
<br/>
In case you can access the configuration file (config/dashboard/dashboard.ini) by yourself, you can open it and
insert the config manually:

<code>
