False Reports

Hello @sicksquirreltwo,

I have scheduled checks on my lab site and would check the same for a few times just to be sure and get back to you with it. Meanwhile, can you go ahead and enable the debug logging to check if that returns any errors which relate to this so we could check if that helps you make it work?

Here is how you can enable the debug log on your site:

Debugging in WordPress

If you do not find ant fatal errors, would you mind doing a plugin conflict test once and then try to check if that works? Please make sure you have a complete site backup before you make a plugin conflict test just to be safe and not lose any data. Here is how you can make a conflict test:

I will also be checking the same on my end and getting back to you with the reports on the same.

Thank you. I can’t edit the files due to disability. I’m either going to have to live with errors falsely showing or finding an alternative plugin.

Hello @sicksquirreltwo ,
Could you share the links with us which are marked as 503?
If not could you let me know if those links are marked as OKAY once you recheck them?

Regards,
Biplav

I manually check each link and they are fine. Several have warnings but are fine. I can’t post the links publicly but could do so in private.

This is frustrating to me but even more so for you. It’s always the 503 error on twelve links though I am not sure if they are the same links every day.

Thank you

Hey @sicksquirreltwo ,
Seems like there’s not much wrong with the plugin as the logs seem to be fine.
It is highly possible that when the plugin crawls this sites they maybe unavailable because the plugin just records what the sites return. I say this because I’ve tried to recreate this as well but I couldn’t do it.
It could be that the sites were temporarily down or when the plugin was crawling.

Regards,
Biplav

Thanks. Other logs show that the site hasn’t been down in weeks. I believe it pings or hits a page every five minutes.

I’ll stop worrying about broken links and just dismiss the bad reports.

@sicksquirreltwo ,
You could set the check interval on the settings for existing links on Settings -> Link checker -> General -> Check each link
https://prnt.sc/s6mtol

Also you can also disable the settings Settings -> Link checker -> Advanced -> Link monitor Then you can disable the Run continuously while the Dashboard is open
https://prnt.sc/s6mviz

Changing these settings should decrease the frequency of the checks.

Regards,
Biplav.

Oops my site checker pings every five minutes, not your plug-in.

@sicksquirreltwo ,
Got it!
But I meant the links that are being checked might be down.
In any case looks like your issue is resolved.
Feel free to create a new thread if you need help with anything else.

Best regards,
Biplav.
