I understand your frustration, but you must understand that not everything wrong with your site is PageLines' fault.
Please see a current Pingdom test just done minutes ago (below)
This shows clearly that nearly 2 seconds of your load time comes directly from the domain, which means it precedes the actual loading of PageLines. As you can see, pageless doesn't even begin to load until after the domain is loaded. That's clearly indicative of a server issue, not a software issue on our side.
Your host has probably assigned insufficient memory resources to your PHP allocation. It should be a minimum of 64Mb, but I'd recommend at least 128Mb. The max is 256Mb.
In the image below, you will see that 77% of your load time is dedicated to waiting. While there is about 1 second wait for pageless, that could be due to memory resources as well, or, it could be due to erroneous CSS. As Jenny pointed out, you did have some mistakes in your site. They can cause a problem. Please consider that before PageLines loads, WordPress must load too. If there are plugins in WordPress, they will, in many cases, load even before PageLines, as they may be part of the operating system, like a cache plugin.
When I replied to you several days ago, and recommended a solution, you didn't mention you had a cache plugin activated. When a change is implemented you absolutely must clear the plugin cache afterwards or the change will not be seen. This is critical, as it makes the support we give you useless until your cache clears. If that's set to 24 hours, you wouldn't see the changes for a day. Most cache plugins operate on 30 minutes, but still, that's half hour you'd not see what we've guided you to do.
I must point out that while James did not post anything further, our developers have been rather busy and didn't reply to him. He said he'd respond when he knew and I assure you that he's excellent at following up. Support in a forum is not instantaneous. It can take days to get replies from busy developers. I apologize for the inconvenience, but that's the honest truth. I might point out that our forums are responded to very quickly, compared to those in other companies where even an initial reply can take days or even weeks.
In conclusion, I recommend contacting the host, and showing them that first attachment I've provided. Ask them to upgrade the amount of RAM allocated to PHP resources. Again, Pageless is not the problem here.
