I migrated site to another server and now functionalists not working like account creation , email registration , checkout etc . On last server everything is perfect. What is going on here ? Any idea ?
There may be any reason but most common issues may be :
1) PHP version issues
Check php version on
old server as well as
To check the php version
create a new file lets say
phpinfo.php at root level of both server
and execute this file like below
2) Check errors in console.
3) Check log files of your website as well as of your
inrsaurabh@maddyboy:/var/log/apache2$ sudo nano error.log
4) Start disabling external extension one by one and check if problem solved.
