  • @phenomlab on a side note, is there any easy way to implement a rule… to allow only two geolocation (countries) but block the access from the rest of the countries?

    @crazycells yes, but without Cloudflare you’d need to perform more checks to determine traffic origin before you have make a decision as to block or permit.

    @phenomlab yes, we are planning to install Cloudflare again…

    We will go with “Pro” version and see how it works, I guess this should help not to have any session errors… Previously, we got many connection problems because of Cloudflare…

    @crazycells I wouldn’t be so sure. The pro version of Cloudflare is $20 per month but I don’t think that will resolve the connectivity issues.

    There also the harm that CF causes to SEO if you use their bot fight mode as I mention here

    @phenomlab I have a good news. We set up CloudFlare Pro, and did not have connection problems yet.

    As you said, it costs $20/month if you subscribe annually, but we did monthly ($25) since we were not sure if this will work for us. So far everything looks OK. We will also check “Google Search” problem you mentioned as well after we secure our forum. Thanks a lot for this warning!

    Unfortunately, we had no choice about Cloudflare since we were getting more than 1 billion connection request from bots and forum was unusable for several hours two consecutive days…

    @crazycells well, of course 1 billion+ requests happened after we installed CF, I do not know how many more we had before installing CF…

    @crazycells Good news in the short term, but interested to see if this does impact the SEO of your forum. Do you have Bot Fight Mode enabled in CF?

    Can you please show me how I reach those?

    @crazycells yes, exactly. You want to allow crawlers such as Google bot etc.

    @crazycells the only accurate way is to use the URL Inspection Tool

    @crazycells it is, yes - I think I’ll leave it as there is no specific PWA CSS classes I know of. Well, you could use something like the below, but this means multiple CSS files for different operating systems. /** * Determine the mobile operating system. * This function returns one of 'iOS', 'Android', 'Windows Phone', or 'unknown'. * * @returns {String} */ function getMobileOperatingSystem() { var userAgent = navigator.userAgent || navigator.vendor || window.opera; // Windows Phone must come first because its UA also contains "Android" if (/windows phone/i.test(userAgent)) { return "Windows Phone"; } if (/android/i.test(userAgent)) { return "Android"; } if (/iPad|iPhone|iPod/.test(userAgent) && !window.MSStream) { return "iOS"; } return "unknown"; // return “Android” - one should either handle the unknown or fallback to a specific platform, let’s say Android } Once you’re in that rabbit hole, it’s impossible to get out of it.

    @phenomlab That will be nice once they have completed that. It will be interesting to see how long that takes. So for now I will use custom css to make it look the way I want. Frameworks just make things a little faster. Thanks @phenomlab

    @pwsincd I think you can use userData.isAdmin = isAdmin; if I’m not mistaken - see https://community.nodebb.org/topic/15128/how-to-hide-whitelist-user-field-only-to-owner-or-admin?_=1648802303112 for an example

    @DownPW the ‘js’ code for the banner takes the time from the client, so what it displays really depends on the regional settings for the operating system. I’ve not seen this issue myself but would like to see some examples of screenshots if possible.
