Hi John,
I had extensively googled the issue and multiple times ran into this max_input_vars suggestion so I had already tried adding the following lines in my .htaccess file:
php_value max_input_nesting_level 128
php_value max_input_time 300
php_value max_input_vars 3000
php_value max_execution_time 300
php_value post_max_size 32M
Unfortunately this didn’t seem to help with my particular problem.
I have found that after I was able to change the field keys back to what they were supposed to be set as from phpmyadmin the fields were saving again. (I looked them up on the staging server where the field keys were still correct since I hadn’t updated the field group)
