Hello friends,

Today after updating php and apache on the server. I was getting below error on my site.

“/usr/bin/php: symbol lookup error: /usr/local/lib/php/extensions/no-debug-non-zts-20060613/suhosin.so: undefined symbol: zend_atol”

The error message appears when an old application or software is upgraded to latest version. It may not cause issues with all the applications but definitely does affect some of them.

The only works when you enable suhosin.simulation for the account instead of disabling suhosin on the server.

You can perform this task by following ways :-

1.  By enabling suhosin.simulation in .htaccess file. If  susphp is not enabled on the server.

php_flag suhosin.simulation On

2.  By creating php.ini file under public_html/ directory. If  susphp is  enabled on the server.

suhosin.simulation On

Now you can check your application, It will work !!!

If you are getting same error under wp-admin login page then copy your php.ini file under wp-admin/ directory and check once again.
