Relationships don't save when updating

Hello,

You can try to follow this tutorial to increase the PHP setting max_input_vars to fix the issue

If it does not help, can you please generate the PHP code of the relationship and share it here? I will help you to investigate the issue.

Hello,

I will take a closer look.

Hello Emilia,

Somehow the table mb_relationships in the database was deleted so the relationship is not saved after updating the post. I've fixed this issue on your site and now the relationship is saved as well.
