I have scoured all the related "how to apply the security patch" questions already posted and have not been successful. The website in question is on hostgator.com and I have access to the cpanel.
I have uploaded the patches to the root folder and now I'm trying to execute the command to run the patch files.
These are the two files I have uploaded to the root folder. PATCH_SUPEE-1533_EE_1.10.1.x_v1-2015-02-10-08-20-41.sh PATCH_SUPEE-5390_CE_1.5.1.0_v1-2015-03-03-09-44-37.sh
This is where I am stuck. I have no idea where to access the command line to run the .sh files. Any help would be greatly appreciated since I am a graphic artist and not a programmer. Many thanks, Brian
