SES has many great Plugins that I use, as well as their incredible SpectroMedia Responsive Theme (which is the most truly responsive and fexible Theme you will find).
This Advanced Error Pages Plugin is another one of many of their very useful tools to fill in the gaps of your site to make it look more professional and current. It's flexible and easy to setup too.
Very useful Plugin. Great support. Great selection of Plugins. Overall a great Developer to work with.
These guys always impress me with their plugins and service.
this plugin is perfect like any other from Social Engine Solutions.
Very good service after sale as well.
Thank you very much.
I can say that the most beautiful error page plugin I've seen lately is that we can easily do the editing we want with panic, and I also recommend all those add-ons if you want to get all modules. I think those who want a nice web site really should work with SocialEngineSolutions.
What an important plugin! Do you know how ashamed I was of the standard private and 404 error pages, no, ... Well, right now I couldn't be happier with my website because this plugin makes it look so much more professional! Note I've asked them to consider adding those annoying 'We're Sorry' pages to this plugin. With that addition, this plugin would be complete and a literally a crucial plugin for all social engine websites!
Oh, I didn't even mention they are so great with providing support! They reply generally within 24 hours and are so helpful!
