# Troubleshooting

#### Plugin does not show chart

Please check that the Plotalot Plugin is installed, and that it is enabled in the Joomla Plugin Manager. The Plotalot Plugin must be installed separately from the component and then enabled in the Plugin Manager. There is no free version of the plugin, it is a paid download.

If the Plugin is installed and enabled, but still not working properly, view your article in HTML mode. Some wysiwyg editors make a real mess of things. This is a real example:

```
{plotalot id="39<br />}"
```

If you can't get the article to save cleanly, you might also need to disable Article Text Filtering in Joomla Global Configuration.

#### Plugin variables are not resolved

Again, check your article in HTML mode. Here's another example from a support case. In wysiwyg mode, the plugin call looked like this:

```
{plotalot id="23" P1="_product" }
```

But in html mode it looked like this:

```
{plotalot id="23" P1="_product</span><span style="font-size: 12.16px;">" }
```

So Plotalot was looking for a variable named

```
"product</span><span style=".
```

#### Plugin does not work in a custom HTML module

Check that you enabled the Prepare Content option in the Module options. Unless this option is enabled, the module will not resolve plugins.

#### Only one chart showing

Some types of script optimisation techniques can prevent multiple charts being drawn on a page. The google.charts script tags must not be combined into a single script tag or file. In the case of the JCH Optimize plugin, changing from "Optimum" to "Average" fixes the problem.

#### Errors when saving charts

Errors can occur when saving some of the sample charts if your server has the Apache mod\_security module configured, with protection against SQL injection attacks. A common mod\_security rule returns a 403 (access denied) error if a request includes a SQL "UNION" statement, because UNION can potentially be used as part of a SQL injection attack. See this page for more details:
