Why does my page redirect to the page I requested to appear in the IFrame?
When I attempted to use your PRO version, I wanted to have the IFrame on y site for the Application from a different page. I added the short code of: [advanced_iframe use_shortcode_attributes_only="true" src="https://portal.tenstreet.com/walpole" width="100%" height="600" multi_domain_enabled="false" use_post_message="false"]
I added to my WordPress page @ https://www.walpoleinc.com/application-form/ and if you visit this page you will see that it redirects once loaded to the page noted inside of the iframe shortcode: https://portal.tenstreet.com/walpole
How do we keep this from occuring?
Seems the other page has a iframe breaker. So if you include the other page it will jump out of the iframe and reopens. You need to contact the owner of the other site to remove this script.
in firefox it redirects. in chrome you see this message:
Unsafe attempt to initiate navigation for frame with origin 'https://www.walpoleinc.com' from frame with URL 'https://portal.tenstreet.com/walpole'. The frame attempting navigation is targeting its top-level window, but is neither same-origin with its target nor has it received a user gesture. See https://www.chromestatus.com/features/5851021045661696.
walpole:19 Uncaught DOMException: Failed to execute 'replace' on 'Location': The current window does not have permission to navigate the target frame to 'https://portal.tenstreet.com/walpole'.
so the page in the iframe tries to replace the location. Chrome gives here more rights - but then the whole page fails as the page in the iframe does then not work anymore.
The problem is not the tool. It is the website you want to include. You should contact the owner of the tool and ask them to make the page iframe compatible. So you can use the plugin.
