Try the following steps:
Remove semicolon (;) - which is in the beginning of ";extension=php_openssl.dll"
Save the file : "php.ini"
Click on wamp icon - which can be found on right bottom corner of desktop or tray icon.
Click on: "Restart All Services" then wait for few seconds till wamp icon becomes green which means : "All services running"
Refresh your page that was showing error. Now it will work fine.
jika di php.ini tidak menemukan extensi ";extension=php_openssl.dll"
maka tulis manual dan simpan.
