    @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?

    @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

    @cagatay you’ll need to define this in the body tag (or another element if you want greater or more granular targets) - for example body { font-family: "Poppins"; font-size: 16px; } Essentially, you use the font-size CSS directive.

    @jac That won’t matter. You just redirect at nginx or apache level and it’ll work. The generally accepted standard though is to use a subdomain.
