First of all, we want to acknowledge that it's been about a week this problem persists and we do try our best to pinpoint this issue for your environment. I personally want to thank you for your patience and cooperation and information sharing with us to give ideas what might be the issue.
Your latest reply made me thinking what if our builder cannot handle 50 sections with normal resources, I did a test both on my local installations and one of the live servers by adding 50 sections and adding a simple Alert element inside each. I saved a template of that page and imported to another page on both installations. All of them worked with no issues, both the original and cloned pages.
Then I tried to add a page to your installation with the same template. You can see the page called
Many Sections Test Page.
Unfortunately, on your installation, the sections are not even showing, but the front end shows all the alert elements.
Would you please share the information above with the hosting service provider support and ask them if they have any idea of possible restriction in a number of connections made to a page or maybe there is a restriction of the simultaneously ajax calls?
Unfortunately, our knowledge of the ins and outs of the server configuration of the hosting is limited.
