Recently, I had an issue with my long standing, properly working, physical products, UPS shipping cart. Whenever my pages loaded, any page, a script error would be thrown in Firefox or IE. I tried several computers in my office/shop and my home and each would throw a JS Script Error and NOT load. My customers were unable to make purchases, etc......
This all began around the time you launched the Beta, although I didn't realize the coincidence until today. I was unable to resolve the issue with the shopping cart itself. I tried reloading fresh ones, etc.... I wasn't even fully assured it was the cart at first, even though the error code stated such. I worked on it for a few days and was unable to resolve the issue.
What I found was...... the actual error was coming from the "View Cart" script that allows for the shopping cart to load inside the web page. I removed that script and set up the whole site with a View Cart off the site on it's own page. Not how I like it but I'd rather it works than not.
What happened when this change was made was amazing. For as long as I can remember, my website seemed to load slowly. I blamed it on my site host, I blamed it on myself for over-weighting the pages, etc...... BUT... the moment I removed the View Cart script............ every page loaded amazingly fast. Fast in the order of 4 or 5 times faster. They now flash up into place fully loaded.
I HATE not having the View Cart overlaying my site but I can live with it for the time being. We have purposefully slowed our web sales greatly but are on the cusp of running the business back up the flagpole. I am unsure if having the cart off site is going to be an issue for us or not.
Question is..... Does any of this sound familiar? Has it affected others? I use Homestead Sitebuilder..... is it a Homestead/EJunkie interface issue? What are the facts?
