A recent update to subscribe by email plugin caused a fault with my theme.

The subscribe by email plugin was recently updated and resulted with 404 errors for all my media links. As an admin logged in to the site it suggested resaving the permalinks. This resolved the problem as long as the plugin was not installed. I would really like to use this plugin, can you please help?

The theme I use is a premium theme from Envato called Risen.
I'm very new at all this and the learning curve is very steep. I know that conflicts are possible even when you buy the themes and plugins but hope there is a way to get round it.

Thank you in anticipation, Steve
