Hi guys. Recently I have faced with the following issue.
Given a page has some blueprint which consists of a list of countries, and every country has a list of items inside. So it’s like nested lists. And it worked great.
But now, when I am trying to add one of that items to some country, I am getting ‘Invalid security token’ error. In spite of this, I am able to add new countries, which is like first-level list. Page file is about 50 KB now already. Also need to mention, that manual editing through markdown is working fine.
Is there any way I can fix this? Thanks in advance!
