Checked again, and then double-checked with a friend of mine that knows servers better than I.  Aside from OPcache, there is no server-side caching that I hadn't already disabled.  So re-enabled them because clearly it makes zero difference.

Host provider says they have thousands of clients running the same server config without any issues, so it must be the script.

Again, they blame the code.

Server admins feel their server is never at fault, and coders feel their code is perfect.  Meanwhile, the problem never gets solved while they point fingers at each other.

It's maddening.

Yup.  Unless you can provide specific, hard evidence it's absolutely the server beyond a doubt, they will blame the forum code every time.  Literally providing the exact fix usually helps.

Host provider said it's a problem with the script, and they closed my ticket.

Unfortunately, the problem persists.  I asked members that are experiencing the issue to check the link you provided, and all but two said they're using something other than iPhone.  However one iPhone user confirmed he is using the private relay, the other iPhone user said he is not.

Anyone?

fyi, I disabled Community Maps and error still persists.

I appreciate the detailed explanation Mark.  While the iPhone hypothesis is plausible, I have been experiencing the same issue on desktop, and I don't even own an iPhone.  However it seems to resolve if I log out and then back in again.

I hope your code fix solves the issue.  Stay tuned....

Not sure how you came to that conclusion. Nothing in the errors mentions community map.  Example:

DomainException::0

#0 /system/Helpers/Form/Upload.php(748): IPS\_File::createFromUploads('core_Attachment', NULL, Array, 1.46484375, 0.14474964141846, 0, Object(Closure), NULL, true)

#14 {main}

I'll check.  Meanwhile, why would IP be incompatible with something as commonplace as cache?  I mean, who doesn't use cache?  Seems disabling it is a hack.

What is the real solution?

Nope, you won't either.  It's virtually impossible to replicate.  It's very much hit-and-miss and sporadic  But the frequency of this error is insane.

When you're looking at my error logs, just search by the word "Wrong", and you'll see them.

I don't want to post by error logs, since they show sensitive information.

Nope, I do NOT have varnish cache.

I meant that I have the same symptoms as the OP, but it's widespread across all users, including myself.  Doesn't matter what browser or device they're using.  Same user will have the same issue across desktop and mobile.

Even with all cache disabled, and directives removed from htaccess, the issue persists.  It's a real head-scratcher that's extremely annoying, and costing me members.

Appreciate the suggestion.  I tried it right after you posted. 4 hours later and my error logfile is filled with the same error created during the past 4 hours.  So, that didn't work.

I'm running 4.6.11 too.  I thought the new cookie cache function would solve the problem.  It did not.

I'm at a loss.  Seems disabling all cache has zero impact. I must be missing something, or it's not a cache issue.

I have the same problem, and it's prolific. Many, many users are complaining about it.  Clearing cache and cookies doesn't work, nor does resetting passwords.

I have a dedicated server and a CDN.  I cleared and disabled cache on both to no avail.

I have this in my htaccess file:

ExpiresActive On
ExpiresDefault A0
<FilesMatch "\.(jpg|jpeg|png|gif|js|icon|swf|flv|css|ico|mp4)$">
 ExpiresDefault A2721600
 FileETag All
 Header append Cache-Control "max-age=2721600, public, proxy-revalidate"
</FilesMatch>

<FilesMatch "\.(html|htm)$">
Header append Cache-Control "max-age=300, public, proxy-revalidate"
</FilesMatch>

Not sure if that's causing the issue.  Thoughts?

I'm seeing these errors in my log. I disabled Community Map and they went away. So it's caused by Community Map. What is the fix?

Nope, disregard.

That file is present at /forums/ but not at the base level as the error log shows.

The file needs to be placed at the root level, per https://www.indexnow.org/documentation

What was the solution? I have the same issue.  

Anyone know what's causing this and how to fix it?

That's exactly what I needed.  Thank you!

Well I messed up.  A few months ago, I saw an emailed invoice for Invision Community.  I thought it was for the forum software, which I have on auto-pay. So I didn't pay attention to it.  I just now discovered it was for the renewal for Community Map.

I just tried to pay it, and it said the invoice has expired.  Martin, can you resend me the invoice?  I'll pay it straight away this time!

I'm seeing tons of repetitve errors that say "Only subclasses of Dispatcher can be instantiated"

What is it?
