Could you try to deactivate all other plugins, one at a time, to make sure that there is no conflict with another plugin? You might want to start with cache plugins, as they may have an effect on the form.
Let me know if you find a conflicting plugin!
Is there a way to check this or attempt a fix without deactivating cashie? Last time I did that I spent an entire day resetting everything.
I can’t be sure that your issue is linked to your cache plugin, but since I am not able to reproduce on my own test installation, deactivating plugins will allow us to remove any external conflicts that may appear on your site, and not on a default installation.
You can try to deactivate other plugins first, since the issue might be linked to a conflict with another plugin.
Thank you for your quick response. It appears there was a problem with the width of one of my div tags and the contents of the sidebar was extending out over the button. It’s resolved now.
