Hello! Please perform the following command in command-line and let me know the output:
Hi, I tried this max_input_vars = 2000 and it try to update until the page logs me out.
It worked when I increased to 3000. Thanks.
Hi, i can't see additional directives, where is it ?
Thanks
Hi, @Alexandre Pez.
Additional PHP directives are available for admin account only, see the following article:
https://support.plesk.com/hc/en-us/articles/115000219453-There-are-no-Additional-PHP-directives-field-under-the-customers
In case you do not possess admin access, contact your service provider for assistance.
I kept getting this error when trying to export a large data file from my Wordpress site:
"You've reached your max_input_vars limit of 1000. Please contact your web host to increase it."

This was the solution that worked for me...
