About a year ago, we had a small design group create a new website for my nonprofit organization using the ProcessWire platform. In December, the lead guy announced he was taking a new job and dissolving his company. I am the "expert" at updating the information that was set up as update-able by people unskilled in code-writing, etc. and have been able to change small things like the words within a button by copying and altering the code behind it. (Took me a while to even find where to look!) but I have no access to the home page art work.
We have the need to change a partner organization's logo that appears on the home page, but I have absolutely no access to the back side of that page, other than the text that appears.
Is there any very remedial way someone could explain to me how I can get to the mechanisms behind the home page?
Thanks for any help.
