Can you please show me the actual feed URL?

https://trev.partica.com/website-blue/greg-hocking
It is an xml for this feed https://www.therealestatevoice.com.au/?call_custom_simple_rss=1&csrp_thumbnail_size=large&csrp_cat=21,15,17,18,144,19,141,20,16,170,267,248,-177,-171,-169,-166,-167,-176,-165,-168

Just pulled your feed at my test site and everything works fine: https://d.radikal.ru/d04/2101/86/88eb47634ee8.jpg

I don’t see a problem to fix there. If you think it’s caused by the recent update, you my download a previous version here: https://plugins.trac.www.ads-software.com/browser/cybersyn/trunk?rev=2418869

Also please note that your feed was updated for the last time on January 11th. So it looks like there are just no new posts to syndicate…

It is not caused by the recent update because we were also using an older version when it stopped functioning. clearly there is something wrong with the website then. the feed is working fine, we also tested in our other websites. just so hard to find out what caused the problem suddenly

can you give possible causes for this issue?

can you give possible causes for this issue?

The feed was not updated for 4 days.

you keep on tagging this as resolved, it is not. and you are not being very helpful. please I’m serious here about resolving the issue. can you please at least be kind and offer some explanation that could really help? the feed was not updated for 4 days??

This issue has no relation to the CyberSEO plugin which woks fine (I’ve checked it with your feed by myself). There is no error in code to fix on my end, right? Thus there is some problem with your server or the feed itself (maybe the feed owner has blocked your site IP – I don’t know). I’m not your host admin, so I can’t help with that even in theory. That’s why the case if fully resolved on my end.

you could have given those possible causes earlier instead of answering one liners. we’re the feed owner and I am asking in behalf of the client whose website is trying to pull the feed from us. thanks for explaining further. now you can mark it as resolved.

I’ll tell you more. If you want to avoid possible site blocking, I would suggest to check CyberSEO Pro, which allows you to use proxy servers with multiple IPs; to emulate user agents (pretend to be a web browser, a search engine bot etc); to substitute a referrer URL and to push any post headers (cookies, tokens, session parameters etc) when you pull a feed.
