How to solve the failure of phpcms hash data validation

Phpcms failed to save when modifying individual articles, indicating that hash data validation failed. Let's talk about how to solve it.

1. First find the php.ini file. I put it in the (/ usr/local/php/etc) directory.

2. Then find the max_input_vars parameter and see if there is a semicolon (;) in front of the max_input_vars parameter. If so, remove the semicolon, the value of the original parameter max_input_vars should be 1000, changed to 10000 or 100000, which means to change the max_input_vars to a little larger than before, and then save it.

3. Finally restart the php service or restart the apache service

Refresh the page in the background and save it normally.
