I rolled back to my 4.5.5 site using back ups I had made of the SQL database and the DNN app folder (and to do some offline testing of the upgrade for my site). Through my hosting company's control panel I restored the pre-upgrade SQL db I had backed up and i also recreated the DNN app folder as it was before the attempted upgrade (using a ZIp archive I had made of the relevant app folder). Once I did that and visitied any page on the site I got an "entry 'RequestFilter' has already been added". Can anyone advise what I need to do to restore my website? Thanks
