  • @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?

    @phenomlab I actually do not know yet, because I have not found these settings on the CF yet…

    Can you please show me how I reach those?

    and this is the bot page:

    @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

    @Panda said in Spam spam spam: ok, yes Ive seen the queue, it shows IP, but doesnt have a field for comments from registrant. It’s not designed for that. It merely serves as a gateway between posts appearing on your form or not. @Panda said in Spam spam spam: It would be better if nodebb had this plugin included in ACP list, as not only then do you know its approved and should work, but many people cant or dont want to use CLI on the server That’s a question for the NodeBB devs but in all honesty you can’t not use the CLI when installing nodebb so to be this isn’t a big deal.

    @crazycells hmm. That’s odd. I haven’t made any changes from recollection but I could be wrong. I’ll need to check. EDIT - very strange. I honestly don’t recall adding the below CSS block to alter the bottom bar, but you’re right… .bottombar-nav { padding: 0px !important; } I’ve removed this so it reflects stock Harmony.

    @Panda said in Interesting Widget code, but can’t fetch API: How did you drop that widget into the post there? I hadnt seen this BSgenerator anywhere on sudonix site, do you use it somewhere already? Yes, here https://sudonix.org/topic/414/corporate-bullshit-generator?_=1687774393044 It’s not a “post” or “topic” in the common sense. It is actually a page in it’s own right and leverages nodebb-plugin-custom-pages. This in turn creates a new “route” which behaves like a page, meaning it is then exposed for widgets. @Panda said in Interesting Widget code, but can’t fetch API: Also can you explain more what you mean by calling the code externally. In my API call example, how would I go about doing that? By this, I mean create all the required code in an external JS file that is reachable by the NodeBB instance - so, in “public” for example - or in my case /public/js. The widget then “calls” that file and because it runs outside of the scope of NodeBB, you just need to return the values to the widget. Hope this makes sense?

    @DownPW exactly. Not really a new concept, and in all honesty, not something I’ve ever used. If you consider the need to add links and references, or citations, you’d need to be able to see other parts of the screen!
