P.S. Do not duplicate forum topics

Sorry about dupilcate post.

Is rebuilding the only option?

I noticed Global.ascx had a modified date between the site working and giving the error message.

Actually I don't know. As I've written here I've never been able to replicate it. Try posting this question here

I might have inadvertantly installed Mega Menu. I was experimenting with a different site ( different URL ) and it is quite possible that I uploaded to the wrong site as I use the FileZilla QuickConnect.


However, I'm still having installation issues. I can't currently re-install through my hosting  using the Microsoft Web App.
Sequence failure on the installation page.
Also Create Database not allowed??

I'll try rebuilding from the source code and manually uploading.

I tried installing Nop Mega Menu which i got with the purchased photo video theme in my nopcommerce 2.60 store. It said its compatible, the description file consist of version 2.8, so i replace it to 2.6 so that my plugin list can find it.

But when i try to configure i get the below error

The controller for path '/Admin/Widget/ConfigureWidget' was not found or does not implement IController.

Any help is much appreciated !!

Hi,

As it is described in the NopCommerce Responsive PhotoVideo Theme extension page, the supported versions include 2.65, but not 2.60.

Hello,

The reason for this error is probably because of the name difference between filenames in description.txt file and plugin filename in filesystem. Hope it helps..

Hai,

When I include plugin into the nopcommerce page that time this error where occured
