Whenever I click Save Product for a PayPal Subscription button, it takes a good 20 seconds to reload the page. Looking at my cpanel, I see CPU usage is maxed out at 100% for over ten seconds. I contacted my host and they said this is indeed due to your script. What's going on, and can it be fixed? Thank you.
P.S. The line below this box says "Tags (comma seperated)". It's spelled "separated".
EDIT: upon testing this on a fresh installation on a different site, I can see this problem is unique to one particular site. Can someone send me the site access email and take a look?
