I have a user who is making a massive listing of news articles and discovered that they can no longer add new blocks to one of their pages. Is there a limit on how many blocks can be on a single page? Can this limit be increased?
There’s no limit per se, but PHP does have a limit on how many “things” can be submitted on one page at once, it’s the php.ini setting max_input_vars. Increasing that in your PHP system settings would probably resolve this if that’s the problem you’re having.
After some testing it seems that pages can’t have more than 144 blocks. I have sent a message to our systems department to check the PHP to see if the variable you mentioned can be updated.
