I use Travel insight (free version 1.0.4) for a newly created site for an association. As soon as I modify or create a page I get the following message:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘travel_insight_block_editor_styles’ not found or invalid function name in sitename\wp-includes\class-wp-hook-php on line 286
Our current hpp version is 5.6.4.
Do you have any ideas of the problem? All your suggestions are welcome.
Thanks for your support,
