Hello, dear john5171.
Please, can you tell us in that versions, what the problem is? You said the plugin did not work. Please, can you tell what is the problem? So that we can help you.
thank you.
It is the latest version available. And the settings pages are just showing a blank page. So I cannot change the settings at all.
Hello, dear john5171.
Well, there are several limitations. By this, you can not make a change in the settings.
Thank you.
No, it is a bug. The screens are blank.
I think you should activate debug by typing these lines in your wp-config.php file:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', true);
and uploading it on the server.
You should see some errors indicating what plugin(s) are creating problems and where.
