Ideally you should have your developer apply the patches. Alternatively, please raise a ticket and Dx3webs will apply and ‘best endeavours’ basis. (Please note we will backup your site.. apply the patches and request that you check that all is well. If not the best we can do is to roll back the patches at which time you will need to seek support from your developer).
