I am wanting to serve me website via HTTPS only. This means updating all inks to HTTPS. I am unable to update all links that are using the NextGen Gallery Plugin.
Does anyone know the fix to update all links using this plugin?
I have already tried updating the standard Wordpress URL via the database.
I had the same problem. It turns out you have to clear the cache in the NextGen Gallery.
Go to Dashboard > Gallery > Other Options > Miscellaneous and click the button "clear image cache".
I then cleared out my W3 Total Cache -- just in case -- and made sure my CDN was on development. When I checked it, https: worked and the Gallery images were served securely.
