I just inherited a site where the creator installed the Copperific Theme and then modified the source files to achieve customizations.
My understanding of custom themes was that, in order to protect your modifications, you cloned the original theme and re-named it, housed it in its own theme folder etc. Is that correct?
My concern is that when WordPress updates are available that customizations might be wiped out by the update process.
Additionally looking at the mod dates of the core WP files shows a variety of dates leading me to assume the original developer edited these as well. Is that a reasonable assumption?
Do I have to upload a copy of WP from that version and diff them to know?
What would best practice dictate for this situation.
No code comments, docs, or notes were left for me...
