#1

HI team, please help me tackle this problem.

while trying to login to admin pages, and after the authentication CRIKEY screen with

Uncaught exception 'Whoops\Exception\ErrorException' with message 'Undefined index: �ูล Exif ที่แก้ไขโดยอัตโนมัติ'   
in /var/www/html/staff/vendor/symfony/var-dumper/Cloner/VarCloner.php:89

any ideas how to fix this?

The funny thing is when I

service httpd restart

I’m always able to login without crash.

This may be caused by

zend_mm_heap corrupted

solution:

php.ini -> add or set  opcache.enable=0;
service httpd restart
