I have an old installation of October on local host. When I tried to update it, through http://localhost/octobercms/backend/system/updates

I got the following error

"Use of undefined constant CURLOPT_FOLLOWLOCATION - assumed 'CURLOPT_FOLLOWLOCATION'" on line 440 of /var/www/html/octobercms/vendor/october/rain/src/Network/Http.php

No one ?

In need of helps please.

Install php-curl and after that (not sure if needed) phpenmod curl and restart apache.

Thanks @boriseto. Your comment helped me very much. After install php-curl, error disappeared.

Hi,

I have the exact same error, even after installing php-curl. Any other suggestions for a fix?

Thanks

Hi,

It's been 3 months. Same ongoing issue. Anyone?

Thanks

I have the same issue in the theme installation page

Use of undefined constant CURLOPT_FOLLOWLOCATION - assumed 'CURLOPT_FOLLOWLOCATION' (this will throw an Error in a future version of PHP)" on line 483 of /var/www/elmcareer/vendor/october/rain/src/Network/Http.php

I have the same issue. Anyone?

add

function onStart()
{
    echo phpinfo();
    die;
}

to the code section of a new CMS page and look at the results to verify that php-curl is installed and enabled on the version of PHP that is being used to serve your site.
