If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
I have tested your site, and it loads within a few seconds for me. I also don't see any particularly large images on your site that would cause it to load slowly.
Perhaps you can ask the visitors who are experiencing a problem whether they are experiencing general connectivity problems, and whether they are able to try connecting to your site using a different ISP.
