And, I think I phrased my original question wrong.
What I meant to ask is: where is the best place to write actions/filters that use existing hooks.
From what you say, I guess the answer is anywhere that makes sense.
Very helpful, thank you!
How to I trace through POST requests…?
My host is GoDaddy — they allow you to see your own details.
When I configured my WordPress install to point to the original database, I used the same exact process to find my credentials.
Also, given a separate application is able to connect to that database means the credentials are accurate.
Are there any other steps to take besides updating wp-config when trying to change the database your WordPress install points to?
