Hey there,
Thanks so much for your reply. It has been happening sporadically maybe once or twice a day I have noticed it when loading the site. Definitely not every time the homepage is loaded, but it does happen almost daily. I’m not sure how to be of more help in diagnosing the problem…
I did post about this on the Joomla forums a month or two ago and the only tip I got was: "Perhaps this is some problem between the .js libraries used by your extensions, there are times that call for the same two times or even the same library but different versions." But I wasn’t sure what to make of this…
