Magento 1.9.2.0 problem with patch SUPEE-11086

Question

I have been having the below error when I try to patch my Magento store 1.9.2.0

patching file app/code/core/Mage/Cms/etc/config.xml Hunk #1 FAILED at 190. 1 out of 1 hunk FAILED -- saving rejects to file app/code/core/Mage/Cms/etc/config.xml.rej Could I get some help with this please? Thanks

Answer 1

I noticed the file app/code/core/Mage/Cms/etc/config.xml on my server had been edited manually, <pdf>1</pdf> had been added to the list

<allowed> <jpg>1</jpg> <jpeg>1</jpeg> <png>1</png> <gif>1</gif> </allowed>

So I uploaded a fresh copy of file app/code/core/Mage/Cms/etc/config.xml applied the patch then added the previous changes. Everything works fine now. Thank @Black
