Notice: Undefined variable: hierarchyCategoryGroup

Hello,

I am getting this error in the page where I published the module: "Notice: Undefined variable: hierarchyCategoryGroup in /web/htdocs/www.videodamarte.it/home/components/com_zhosmmap/views/zhosmmap/tmpl/display_map_data.php on line 2795", what can I do?
Thank you and regards

Christian

Hi Christian
Check for updates.
As I can see by code - it is not last version of my extension, at least of component

Hello,
thank you. I actually had installed the new version, but I lost the css modifications I had made, so I got back to the old one. This error comes up only if I set Joomla to maximum error report, so people won't see it frontend, do you think it is a real problem?

Thank you

Christian

Hi Christian
Do not edit my CSS files, just add into your template CSS overrides.

You can store CSS files from my extension, update to new version (to last), and override your stored CSS. It is for case you change my files.

But in future - compare and find out your CSS changes and move it to template
