I'm still getting this error repeatedly, almost always by the same IP address, or maybe same few, but specifically one hits it a lot. One of them typically hits it 6 or 8 times a day, anywhere from 20 minutes to 50 minutes apart. Then the next few days, they produce the error 0 to 4 times (per day), then it will be a week or 2 with nothing, and then the same cycle happens again. The other IP addresses probably hit it half that much.
I know Illori said last time not to worry unless it's always the same address. And it does seem to always be the same -- at least one is always the same. I'm pretty sure the others repeat too, but I didn't write them down to be sure.
If I could only figure out what link they are clicking, I think I would feel better. But I don't think it is a link, that they aren't really human visitors, and that there's some script behind it. It's always the exact same error message, from the exact same IP address (maybe more). Well, there's one variation on it with a different URL and different Line in the code. But it's mostly one of them.
I tried looking up the IP address in whois, and it's reg'd to wowrack.com, which looks like a regular webhost, related to Tucows, which I know is reputable. So that doesn't seem so bad. But why would they be scripting into my site, to a URL which they've been informed probably hundreds of times by now, produces an error?
Ooh...my domain registrar is Hover, which I think is related to Tucows as well....it seems like I saw that somewhere. But why would the registrar do this? If I only knew what "this" is! Doesn't anyone else get this error? And equally gnawing question, why is it aimed at TP? Or is it only TP that is reporting it?
I tried searching the end part of the url, which doesn't include my domain, but no luck there. No full matches.
Do you think I should just block them? Or is there some way to find more about it first? I have analytics, but so far, I haven't seen the errors on the same day they happen. And the analytics seem to only be saved for a day. (Well, I know I can save logs if I want. I just haven't done it yet.)
Anyway, should I still not worry? Or should I worry a little?
Thanks for your help
