Hello @elliekennard,
Thanks for sharing all the details. After receiving your concern we have proceeded with some tests and we haven’t able to reproduce your mentioned scenario. In this case, it may cause by the internal theme or plugin conflicts.
Note: It’s highly recommended to take a full backup before proceeding with the conflicts test.
The following section provides instructions for determining if an issue you are experiencing is caused by a theme or plugin conflict.
1. Theme Test
=> Switch to the default WordPress theme as we know that the default WordPress theme is coded properly. Now try again and see if the issue is still there. Take note if you see a difference in behavior after you have switched the theme. Switch back to the theme you were using.
2. Plugin Test
If the theme didn’t have anything to do with the issue then move on to the plugins section. There are many WordPress plugins out there and not all of them are coded nicely so let’s see if you have a plugin installed that is not playing nice.
=> Try to deactivate the plugins excepts Subscribe2 then check again.
Let us know how it goes for you.
