Limit to Number of Option Values?

Is there a limit to the number of values an option can have? I have an option called "Blocks" that has 101 values. When adding the option and values to the product, I can add 63 values. As soon as I try to add the 64th value and click save I am redirected to the system dashboard and the value is not saved.

I found this in my logs:

AH01071: Got error 'PHP message: PHP Warning: Unknown: Multipart body parts limit exceeded 1020. To increase the limit change max_multipart_body_parts in php.ini. in Unknown on line 0', referer: www.flint3d.com/administrator/index.php?...ask=product.edit&cid []=37

I think you fixed a similar problem on a different site for me. Not sure how though.

Hello Nicholas Flint,

Thank you for submitting the question here. There is no limitation of number of option values. I think the problem that you have caused by the setting value max_input_vars of your hosting server. Default value is 1000. Please contacting with hosting provider to ask them to increase this setting value to a bigger number (example 10000 or 2000), then you can add more option values to product and save them normally.

Sincerely, Giang
