Getting Security Error on iPhone when using localStorage

When I try saving anything with localStorage.setItem(""); in IOS Safari, I get this error -

SecurityError (DOM Exception 18): The operation is insecure.

Here is a screenshot of the error...

Any ideas how to fix this? Thanks.

It's not only Safari, but also Firefox in private browsing mode. Chrome doesn't block localStorage in incognito mode, but it is being reset at each session (which is a better option imho). In either case, you shouldn't use localStorage directly, but instead make a script that uses it if it is available, and if not, then use sessionStorage. I.e.

var backupStorage = {};
var storageMode = 'localStorage';
try {
    localStorage.length;
} catch(e) {
    try {
        sessionStorage.length;
        storageMode = 'sessionStorage';
    } catch(e) {
        storageMode = 'backupStorage';
    }
}

function setLocalStorage(key, value) {
    switch(storageMode) {
        case 'localStorage':
            localStorage.setItem(key, value);
            break;
        case 'sessionStorage':
            sessionStorage.setItem(key, value);
            break;
        case 'backupStorage':
            backupStorage[key] = value;
            break;
    }
}
function getLocalStorage(key) {
    switch(storageMode) {
        case 'localStorage':
            return localStorage.getItem(key);
        case 'sessionStorage':
            return sessionStorage.getItem(key);
        case 'backupStorage':
            return backupStorage[key];
    }
}

I had this problem on the desktop version of Safari. I enabled "Disable Local File Restrictions" This is how you can find it:

where to find "disable local file restrictions" in desktop safari

Your cookie settings are also not allowed to be on "Always block". Otherwise you also get this error!

Found the answer. Block Cookies was turned on in the users Safari Settings.
