I am not the developer and I need to deploy a solution by add-SPsolution with WSP file. I don't have Visual Studio to make change like Overwrite="TRUE"
During my first deploy, everything goes fine except the page loading the custom solution (a user control) throw error.
So I tried to Deactivate the solution in Site settings -> site collection solution. Then re-activate again to find the titled error..
What can I do? Do you think remove entire site collection and re-create can fix?
