I recently upgraded our site to 3.4. First issue I had was that I was brought to a screen after upgrade for new settings that needed to be configured. I selected the options required, hit 'Save' and then it just kept me on the same page. I had to change my URL to the default directory to get out of it.
After a few days, I received a notification that there were updates to some of our plugins. Clicked on 'Install Available Updates (4)' button, at the next page I get all of the Warning messages that the folder already exists and will be overwritten, I then click the 'Continue' button.... and then it takes me back to the Notifications page. It never completes the upgrade.
Any help would be appreciated.
