Hi Richard!
Thanks so much for the quick reply.
Followed your very easy to follow instructions and now there are NO files in
/home/******/public_html/wp-content/cache/supercache/example.com/
SO...
Let's see if I understand what's going on / how to best handle in future:
If you need to do a lot of work on a site and want to ensure that caching is NOT interfering, the best method is to follow the steps you outlined.
If you simply deactivate WP Super Cache, it's going to retain the old cache.
Therefore, when done with development, simply go back to the Easy tab and turn caching back to on.
CORRECT?
Finally...would there be ANY reason why WP Super Cache would interfere with / block an icon font? There are only a very few other variables on this particular site besides the presence of WP Super Cache, whereas my implementation of an icon font worked every where else but not on this site.
Thanks so much for your help!
