Thanks @jplew that did the trick! However I wasn’t getting any PHP Warnings in my error log – in fact I’m getting no errors when I save the form which is strange.
Initially I thought my solution of deleting and re-adding entries worked but I hit the same brick wall a few days later. I had come across max_input_vars previously but it was commented out in my PHP.INI so naively assumed it was Unlimited. Here’s what I’ve added in my .htaccess to fix the issue:
php_value max_input_vars 3000
php_value max_input_time 120
php_value max_execution_time 60
I’ll have to keep an eye on it but hopefully 3000 is high enough to avoid this problem occurring in the future.
Thanks for all the help guys
Chris.
