    Hi, I cannot attach a Nextgen gallery to a post anymore. When I am editing a page and click the button “Attach Nextgen Gallery to post” I get an error: Error thrown Call to a member function add_settings_page() on null. Could you please help to solve this?

    The page I need help with: [log in to see the link]

  • Hello @barbarab123,

    Let’s first check if it is an existing conflict:
    – Temporarily deactivate all your plugins except NextGen Gallery.
    – Is the problem solved? Then, it was caused by one of your plugins. Please check one by one and find the one causing the problem.
    – If the problem is not solved with the deactivation of the plugins, try changing to a standard WordPress theme, it could be a conflict with your current theme.

    Note: a full website backup is encouraged before checking for conflicts.

    I have a similar problem. I can’t edit any page I get the message “Error thrown Call to a member function add_settings_page() on null”. When I deactivate “Woo Commerce” I can edit pages. Is there a solution to this?
