Hello Ronny Ko

First, download SP Page Builder Pro from your downloads and then install on your site again. Then copy the 32-digit license key from your dashboard and activate your license in SP Page Builder settings on your site. Then clear cache and browser cache. If the above tip does not help, then please follow this documentation

Best regards

I followed all the instructions. I can say that before I renamed the file to .htaccess per these steps, the Add Sections was working. do you think or agree with me?

Your server may have set too sensitive security level settings from its firewall, or [I don't it's the issue] PHP file_get_contents() function has been disabled/locked [I don't it's the issue]

• in that case, please contact hosting support. ** In most cases can be changed in php.ini or .htaccess file or ask Hosting support.

I am not sure about it. Turning off mod_security could be a solution. Please follow the above documentation.

I'm sorry, but we don't have CPanel. We have PHPMyAdmin. Woudl that be useful to turn off mod_security?

I do not know where the setting is. You should contact your hosting provider for assistance.

Ok, when I open the console under MS Edge Inspect, I get

index.php:63 

       Uncaught SyntaxError: Unexpected token '.'

What does this mean?

Would love it if you went to the administration page to help me a little bit.

Ok, I have turned off Mod_Security in apache. It didn't work. Add Sections in SP Page Builder still doesn't load.

Interestingly, I have another side with pretty much the same configuration. and the treatments were identical. In that site, Add Sections in sp page builder works -- which means the content loads! So, I tried deleting the SP Page builder component in the terminal. All my pages were gone too. Too destructive. I feel that a clean reinstall is needed. Please tell me how to do it without losing everything in SP.

I have backups in my Docker containers -- yes, Joomla is running inside Docker.

I await to new ideas, if any.

<IfModule mod_security.c> SecFilterEngine Off SecFilterScanPOST Off </IfModule>

I have checked your site and took a backup. Then checked it on my localhost. Here, section loads fine. I have found the same Console Error like you Uncaught SyntaxError: Unexpected token '.' So, it is clearly not the issue here. It is definitely something with the hosting. Please follow this documentation again and check each steps. Hopefully, this will help.

I have gone through every single bullet in your documentation page. Everything is as it should.
Since you were able to make it work && my other website that's running on the exact same server in a Docker container is running, I also created a new docker container, used Akeeba backup to backup and restore the site on the new container, the result was the same.

So, what was your backup and restore process that made it work on your side?

I have not got much experience with docker. I have checked on my localhost with MAMP Apache server.
