Hello, thank you for for taking the time to take a look on my issue.
I tried the recommended suggestions. But the issue is still there. Increased the memory_limit to 512Mb, enabled and disabled plug-ins, and everything is up to date.
When I open the editor in the orginal version (english) everything works fine, I can edit with cornerstone without any issue, when I create a new page and create a simple translation it works, the issue appears to be on the pages I already created with translations, not being able to open and get the error you mentioned.
Is it possible to try something different? I'm not able to recreate all the pages already working, I just need to show the new home page with all the sections.
Thank you again.
