I recently upgraded our DNN installation from 4.5.5 to 4.8.4. We've used DNN for many years now and have established an upgrade procedure. We maintain the version number in the IIS, physical directory name and database name.
For example, our the DNN directory and Database name before the upgrade was similar to DNN_4_5_5. For the upgrade, we should copy the entire directory and database to a new directory and database called DNN_4_8_4. We would then upgrade the new directory as specified in the manual. We do this in case we have problems we immediately revert back to the "untouched" older version.
Up until this last upgrade, we have not had any problems. However, after this last upgrade we found that when an admin user uploads a file using the File Manager under the Admin tab, the file is uploaded to the "OLD" DNN_4_5_5 directory.
Here is how i discovered this. One of our users uploaded a new image used in a skin and noticed that it did not change when refreshed in IE. We discovered the problem after they notified us and copied the image from the old directory to the new directory. Once the image was copied, it showed up when we refreshed IE. This tells me that DNN is pointing to the new (correct) web directory, but uploads are going to the old (wrong) directoy.
Does anyone know why it is posting to the old directory?
