Enfold avia layout builder keeps loading on all pages

Attached the server settings below.

Yep, I’ve updated to the latest version from themeforest via FTP. Unfortunately I don’t have a local server set up at the moment to test on.

Any common causes for this that can be eliminated?

Sure, I’ve attached it to the private content below.

Hi Jordan, I’ve just done that.

Sure, the file exists. I’ve posted it below:

Hi John, that’s strange. I can edit that page, and also add new pages, but I can’t edit existing pages. Can you try for instance editing the homepage?

Hi, managed to get it working in the end. The issue was caused by the hosting environment.

Their explanation was:

The issue was caused by triggered Mod_Security rule. We have Mod_Security installed on our servers for security purposes. It is an Apache module which works as a web application firewall. It blocks known exploits and provides protection from a range of attacks against web applications. Sometimes, due to the poorly coded script or any other script related error, mod_security may incorrectly determine that a certain request sent to the server (that matches mod_security rules) is malicious, while it is legitimate actually. We have whitlelisted such a rule for your cPanel account.
