Infopath Publishing error "The following URL is not valid"

When trying to publish Form the following alert appear "The Following URL is not valid"

Solution: 

After Googling and trying lots of things, I remembered my proxy was turned on at University...

Check if it's active, if so deactivate the proxy server at IE

Internet Options - > Connections - Lan settings - > "Proxy server" - deactivate the check boxes here

Have a great Day ;)

Hi Folks,

One day in the morning I keep getting this error: The breakpoint will not currently be hit. No symbols have been loaded for this document.

I asked for help on a Microsoft College and He simple did "nothing". After 30 minutes it started to work and the only different thing he done was this:
Solution:

1. Go to Menu build -> Configuration Manager
2. In the Active Solution Configuration, select Release (or Debug if you had Release). Close
3. Do a Clean Solution then a Build Solution
4. Switch back to to Debug (or Release if you had Debug).
5. Now if you deploy the error will go away.

Hope it helps for you folks

Error occurred in deployment step 'Activate Features'

On the Quality Enrivonment i created a new Project in Visual Studio and when deploying this message appear:

"Error occurred in deployment step 'Activate Features'"

Solution is to deploy it manually for the first time:

1. Add the solution to your Farm Add-SPSolution -LiteralPath
2. Then Install Solution Install-SPSolution -Identity -WebApplication

After that you can deploy automatically using Visual Studio. Enjoy
