DrByte:
There are all kinds of choices.
As suggested earlier, one approach would be to progressively copy customizations from the modified site to the test site and see when the slowdowns happen.
Hi again....
I have been busy with other projects....
I found that by simply copying the (customized) live site files to a new folder, and then adding the admin and cache files from a clean version, the Admin works perfectly.
I started looking around / comparing files. So far, nothing. I plan to comprehensively go through everything, though...just not this week!
Well, at least it works.... :smile:
When / if I find out more, I will certainly update. Thanks again everyone!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
