I am working on configuring PHP and Apache for my site and I am running into an error that I do not know how to fix. Here is the error I am getting in the Category module.

Strict Standards: Non-static method modEasydiscussCategoriesHelper::accessNestedCategories() should not be called statically in /home/leagueses/public_html/modules/mod_easydiscuss_categories/tmpl/default.php on line 20

Can anyone give me some direction on what to look for that I need to change or edit on my server configuration to fix this?
