I've modified a minor bug in a User Control of a custom SharePoint solution that was initially deployed on SharePoint 2007 but now it is deployed on SharePoint 2010.
I was hoping to just update the affected parts of the solution, so I copied all the dlls and user controls to the web application virtual folder, I made sure I didn't forget files in Features folder under 14 hive, and I restarted the server.
However, the changes I made are not being recognized at all. I thought of deactivating and re-activating the feature but I can't see it neither in Farm or Site collection features lists. This is actually the same case on the production server. But the front end works fine both on the production and development servers except for that small bug I mentioned above. Also Visual Studio is not showing any debug or build errors.
Please suggest any idea.
