I am newbie in Laravel. I am using windows 7. I have downloaded and created a laravel project inside xampp inside htdocs folder.I have uncommented the statement,extension=php_openssl.dll inside php.ini. When I type the http://localhost/laravel/public/ in the browser, it shows the home page. When I refresh the page I get an exception like this.
When I remove the cookies and session variables in the browser settings, it will show the home page for once and if I refresh the page after,it shows the above page again.
NB: I have edited nothing in the project.I just tried to run the project
After uncommenting the line in the php.ini file, you must still activate it: left click on the WAMP server icon, then PHP-> PHP extensions and ensure that php_openssl is checked. If not, click it. WAMP will restart and it should be OK.
