The WP submission form can no longer be used due to SSL authentication settings.

The plug-in used by WP is called "MW WP Form".
We are using an old version with the current MW WP Form version 4.0.5.
The latest version is version 4.2.0.

Is it possible that the older version can no longer support the old version due to SSL authentication setting?
I thought that once I gave the version, I couldn't cope with any further problems
Because it will become, I am wondering whether the version should be upgraded.

If i am familiar with MW WP Form, please let me know.


Despite being redirected to https due to SSL settings, it was submitted with http.
It was solved by changing the URL setting to https.
