i receive this error in advanced pdf template during customization The entity name must immediately follow the '&' in the entity reference.

AI generated answer (using internal Slack threads):

The error message you're encountering, "The entity name must immediately follow the '&' in the entity reference", is typically due to an issue with the XML syntax in your Advanced PDF template. This error often occurs when there is an unescaped ampersand (&) in your XML content. In XML, the ampersand character is a special character used to start an entity reference (a way of representing characters). If you have an ampersand in your content, it should be followed by an entity name and then a semicolon (;). If it's not, the XML parser will throw an error because it's expecting an entity reference but doesn't find one. To resolve this issue, you should escape any ampersands in your XML content that aren't part of an entity reference. You can do this by replacing the ampersand with

&

. For example, if you have a URL in your XML content like this:

code block
<http://example.com?param1=value1&param2=value2>

You should replace the ampersand with

&

like this:

code block
<http://example.com?param1=value1&param2=value2>

If you're not sure where the problematic ampersand is in your XML content, you can use an XML validation tool to check your XML for errors. These tools will typically highlight any issues with your XML syntax, which can help you find and fix the problem. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
