Question error message

Hi,

I have a strange error. I got this message:
The error appears when I try to open the page of a person, but not at other persons. When I am logged in as guest, the error doesn't appear, and also not when I am logged in as administrator. The error appears only when I am logged in as normal user.

What can be the problem?

Probably this: webtrees.net/faq/thumbnails/

Maybe, but in that case I should think that there should be also an error when I am logged in as administrator ...

> Maybe, but in that case I should think that there should be also an error when I am logged in as administrator ...

Do you use watermarks on your site? These require more memory. The administrator does not see watermarks.

I have done some tests with the watermarks settings in control panel>trees>preferences.

There are 4 options. With none of them the page is show for normal users, but I see it as administrator. If I choose "hide from everyone" I have a watermark on the picture (but the page isn't shown to users). I should think there shouldn't be shown a watermark in that case.

The picture itself seems not very big, 100x120 px.

Do you have other suggestions?

Do you still have that error about not able to allocate any more memory?
You currently have a limit of 128mb which is rather low. I think with a php.ini file you can raise that, perhaps 160mb would already be enough.

Also i'm puzzled where exactly it goes wrong. What do logged in users exactly see?

Could you try these strategies to get more error details?
webtrees.net/faq/500/
webtrees.net/faq/xhr/

The memory seems not to be the real problem. I raised it to 1048. In the admin mode the page opens correct. In the user mode I got now a 503 error.

Later I will look to your other suggestions.

Another thought, it might be an image from a source giving the issue.
Visitors by default don't see sources, but members do.

How can I test / see that?

Switch off the watermark feature and test whether the page loads for members. If yes, you're closer to finding the problem.

Watch the whole page & sources of the person, look for other images than the portrait.

As mentioned, I tested the watermarks before.

I use PHP8.2.

With memory 512 or higher I got error 503 from the server (not from webtrees).

With memory 128 or 256 I got this message:
I was thinking:
On the page (and on an other page where was an error) there was a picture with a filename without extension. I added the extension. But still an error. Can I clean anywhere the cache or the thumbnails?


++++++
NEW / EXTRA info
Maybe can the following be the reason of the error. There is a source and the "text" of the source should be hidden (it has confidential information). Probably that possibility is outdated or was never allowed.

Code:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 479232 bytes) in /home/.../public_html/webtree/app/Media.php on line 54

The naieve approach would be to first try what happens with max memory set to 511 or 500. Give it substantially more than 256mb, but not enough to go beyond the maximum allowed by your provider, and cross fingers that is enough.

Another slightly more intelligent approach is figure out what webtrees is trying to do and come up with a hypothesis why this takes so much memory.

This is the code around line 54 of Media.php :

I think the code chokes on a record (indirectly?) referencing itself, creating an endless loop.

Worth a shot: export your tree as GEDCOM file, import in a new tree.
Navigate to the troublesome person in the new tree.
Most errors related to corrupt or illogical data are solved this way.

I'm curious how exactly you fixed this. Using the dialogs in webtrees? Doing SQL UPDATE statements and fumbling with files in the media folder?

The most error prone way I can think of, is to just remove the image and add it again, only using webtrees dialogs.
Actually, when logged in as an administrator you probably can do that!

Hi Bert,

Pictures:
The name of the file I changed as "admin". You can change in webtrees the filename. But the problem seems to be not in the image. (see under)

Other Individuals:
I found an individual without media objects but with the error.

Import GedCom:
Before I export/import the GedCom I should like to know what risks there are. Or better how to handle the media connected to the database.

> I found an individual without media objects but with the error.

What is the exact error message on that record? Where exactly does it go wrong?
Is that person perhaps linked to the same source as the other person?

If you import into a new tree (and have a database backup ready to restore, just in case) the risk is close to zero.
 

I made an new tree from the exported gedcom. Still the same problem. I tested the user rights for this tree. As visitor no problem. As member, editor and moderator I get the error. As manager it works again.

Right...

What happens if you remove this media object completely?

Is it a software bug or not?

Finally I found the problem and I could repair.

The problem was a loop between a media-file and a source. But first it was difficult to find out were to search. The media-file was connected to a family. But that made that the children as also the grant-parents of both sides were not visible.

Why was there a loop?
I had a marriage picture. I published the whole picture as also the out-cuts from the individuals. To make a connection I made a source and connected the source to the 3 media object. But when you add a source you can add to that source a media object. (see   ) In this case the same. That give not in the administrator mode a bug, but in the member mode it does.

Maybe a good idea to check the program?
