Hi!
I've been out for a while, and not working with webdesign at all for some time. But now I'm back, and just to find an issue I am not sure on how to solve, while updating a website.
The following error appears on top of pages:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'uk-flex' not found or invalid function name in /home/tupodesp/avalforma.pt/wp/wp-includes/class-wp-hook.php on line 286
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'data-uk-slideshow' not found or invalid function name in /home/tupodesp/avalforma.pt/wp/wp-includes/class-wp-hook.php on line 286
Any clues? Can someone help me with this?
Thanks in advance. Saul
