Troubleshooting
Debug your plugin.
The first error may be because that Plugin or theme is not using Current WP compatibility jquery and that will create MAP ISSUES. We posted a blog about that here and here is additional info on WP about 4.5 issues, Check PhP versions, they should be updated per WP best practices see info on what you can do to request that from your host.
You have FAILURES,, using any Inspect tools from your browsers (See the Debug video or Docs in Troubleshooting)
the first one noted here is a result of incorrect html reference with lightbox . Is this part of your theme? Is it using an outdated jquery version that may not have shown errors before , but now will with latest WP 4.5 updates . See that WP link above for more info .
jquery.colorbox.js:13 Uncaught ReferenceError: lightbox_html is not defined
**This next error mentions multiple Google MAP APIS, you have more than one plugin loading and trying to connect to Google Maps and this is a conflict with SLP.
js?language=pl&ver=4.5.03:92 You have included the Google Maps API multiple times on this page. This may cause unexpected errors.
