I'm having troubles updating a patch and was hoping to get some advice. These are the instructions I've been given to update (full documentation:http://pkp.sfu.ca/ojs/UPGRADE
To update by patching, download the appropriate patch file for your current version of OJS and run the following command from your OJS directory:
$ patch -p1 < PATCH_FILE
But...I have no idea how to run a command from my OJS directory (which I believe is just a folder on my server). Anyone have any ideas?
