Unable to access my website

Hi there,

I’m having a problem accessing my website. few error messages appears such as:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘maxbuttons_fields_class_paths’ not found or invalid function name in /home2/smaweb/public_html/wp-includes/class-wp-hook.php on line 298

Warning: array_merge(): Argument #2 is not an array in /home2/smaweb/public_html/wp-content/plugins/so-widgets-bundle/base/inc/fields/siteorigin-widget-field-class-loader.class.php on line 60

It messes up the whole site and i unable to access the admin account of it.

Is there any way to fix it and explanation that cause this?
Here’s my website nourishsr.com
Thank you very much.

Hello @kamens,

Please create a full site backup, deactivate all plugins except Sydney Toolbox and Page Builder by SiteOrigin, and see if it helps.

Here are some helpful links:
