Error in Slider

Hi I'm new here but I'm having trouble with my website.

The following happens, I put the photos on the slider in the right size and everything .... and it worked the first time.

But recently I switched the pictures of the slides again only this time the slide is locked in the first picture ever.

Already tried everything, does algue could help me please

Hello!
I have the same problem with Beauty Secrets theme.
Website is http://bezpremudrostey.ru.

Could you help me, please?

Hi!
You can try to detect the problem by editing wp-config.php in the root directory of your WordPress. Just find string:

define('WP_DEBUG', false);

and replace it with:

defined('WP_DEBUG', true);

This function shows the errors occured on your website.
Besides, try to disable all the plugins you use. It may be caused by a compatibility problem.

The function shows the folowing:

Notice: Undefined variable: layout in /home/***/domains/bezpremudrostey.ru/public_html/wp-content/themes/beautysecrets/inc/library.php on line 172

Notice: Undefined variable: format in /home/***/domains/bezpremudrostey.ru/public_html/wp-content/themes/beautysecrets/inc/library.php on line 454

Oh, thanks!
It starts working after I've switched off some plugins)))
