SSL issue on nginx

There are only 2 Yellow icon messages:

Mixed Content: The page at ‘…/kasa/’ was loaded over HTTPS, but requested an insecure image ‘…/przepisy2.jpg’. This content should also be served over HTTPS.
(index):1 Mixed Content: The page at ‘…/kasa/’ was loaded over HTTPS, but requested an insecure image ‘…/aaaaa.jpg’. This content should also be served over HTTPS.

The only warning that shows up is the one about the insecure image. If you want me to show it to you please provide me with your email so that I can send you the password to the website.

No errors to shown there. See above attachment.

Ok I have found some stuff that is odd in that section.

/* <![CDATA[ */
var WofficeAutocomplete = {"url":"https:\/\/sedziapilkarski.pl\/wp-admin\/admin-ajax.php"};
/* ]]> */

or

/* <![CDATA[ */
var wc_address_i18n_params = {"locale":"{\"PL\":{\"postcode_before_city\":true,\"state\":{\"required\":false}},\"default\":{\"first_name\":{\"label\":\"Imi\\u0119\",\"required\":true,\"class\":[\"form-row-first\"]},\"last_name\":{\"label\":\"Nazwisko\",\"required\":true,\"class\":[\"form-row-last\"],\"clear\":true},\"company\":{\"label\":\"Nazwa firmy\",\"class\":[\"form-row-wide\"]},\"country\":{\"type\":\"country\",\"label\":\"Kraj\",\"required\":true,\"class\":[\"form-row-wide\",\"address-field\",\"update_totals_on_change\"]},\"address_1\":{\"label\":\"Adres\",\"placeholder\":\"Ulica\",\"required\":true,\"class\":[\"form-row-wide\",\"address-field\"]},\"address_2\":{\"placeholder\":\"Nr mieszkania, lokalu (opcjonalnie)\",\"class\":[\"form-row-wide\",\"address-field\"],\"required\":false},\"city\":{\"label\":\"Miasto\",\"required\":true,\"class\":[\"form-row-wide\",\"address-field\"]},\"state\":{\"type\":\"state\",\"label\":\"Stan\",\"required\":true,\"class\":[\"form-row-first\",\"address-field\"],\"validate\":[\"state\"]},\"postcode\":{\"label\":\"Kod pocztowy\",\"required\":true,\"class\":[\"form-row-last\",\"address-field\"],\"clear\":true,\"validate\":[\"postcode\"]}}}","locale_fields":"{\"address_1\":\"#billing_address_1_field, #shipping_address_1_field\",\"address_2\":\"#billing_address_2_field, #shipping_address_2_field\",\"state\":\"#billing_state_field, #shipping_state_field, #calc_shipping_state_field\",\"postcode\":\"#billing_postcode_field, #shipping_postcode_field, #calc_shipping_postcode_field\",\"city\":\"#billing_city_field, #shipping_city_field, #calc_shipping_city_field\"}","i18n_required_text":"pole wymagane"};
/* ]]> */

Are those slashes correct? \/ \”

That’s the only weird thing I can find in the output.

I think I do, and all I get is the entire code. Have a look:

http://s10.postimg.org/8lhqmbue1/screen234.jpg

I saved the permalinks, delete the cache but it is still showing the HTML

location / {
		# First attempt to serve request as file, then
		# as directory, then fall back to displaying a 404.
		try_files $uri $uri/ /index.php?$args;
		# Uncomment to enable naxsi on this location
		# include /etc/nginx/naxsi.rules
		include /var/www/nginx.conf;
	}

NGINX is allowing it but it is still not showing. Do you want me to give you the link to that website?
