Recurrent empty error

[Webmaster Scr]

Hi,

For several months now, I have very regularly a blank error that appears:

There is absolutely nothing in the logs:

The site seems to work perfectly well (at least I don't see anything wrong with it). But when I delete this error, it always comes back after a day or two.

I tried to change the settings (setting log level from 1 to 5) but it changed nothing.

What is your prune timeframe for the error log? Just wondering if it is clearing by the time you are checking the actual log.

[Webmaster Scr]

It’s 4 weeks.

Sorry, I think there may actually be confusion here. If you are looking at a completely blank page, it will not have got that far. It would be in your server error logs

[Webmaster Scr]

I check my admin page every days and these errors are always empty as soon as they pop, so I doubt the problem could come from that. 

[Marc Stridgen]

Im not sure what you mean there. If the page is a white page entirely, it means PHP encountered an error and was unable to render the page

[Webmaster Scr]

I don’t know. You have a screenshot above. I’m not a programmer, so I’m unable to tell you how it happens.

The error is still available on my system if you want to check. 

[Webmaster Scr]

The error is still there: did you find where it comes from?

A PHP white (blank) page means that there are some errors in your PHP code or configuration, but they are not displayed in the browser. This can result in a blank screen or an HTTP 500 error. Such php errors are not logged in IPS system logs.

To troubleshoot this issue, you can check the error_log file in your website’s document root or logs folder. You can also enable error reporting in your PHP.ini file.

If you are not sure how to do so, it's better to ask your hosting provider to take the action.

According to my cPanel settings error reporting is already on:

I checked ~/public_html/error_log and there was no recent relevant error in it. The last one was very old while I got another "empty error" yesterday.

Same thing for server error.log, the last entry was older than yesterday:

[Tue Jun 06 01:42:10.063537 2023] [cgid:error] [pid 2534:tid 47697533363968] [client 198.167.198.xxx:0] AH01265: attempt to invoke directory as script: /home/Scr/public_html/cgi-bin/

So I really wonder where Invision got these errors.

Im not actually seeing any error in your admin notifications at present. I would simply dismiss that if you have only see it the once, as you are likely chasing something that is no longer present

[Webmaster Scr]

Yep, that’s weird: the notification exists on my Admin login (screenshot took 2 minutes ago):

But not not on the Admin login you use: 

Are notifications allocated to the first Admin to open/see them?

And, no, it wasn’t an isolated case. These errors recur every 2 or 3 days when I delete them.

They shouldnt no. Are you happy to add your login details on file, so we can see this issue?

Done (I wrote instructions in Notes field).
