Hello,
From time to time, my website host changes the MySQL version.
I have to rerun the setup.
After redoing the setup and putting the site back online, some of my VR album titles were replaced by
"charset = Ascii {"info":{"gyro_stabilized":true,"initial_view_changed":fal "
Some images keep their titles.
The involved album contains copies of images from other albums (for pc or smartphones)
I would like to understand why and how to prevent this in the future.
Problem comes from metadata:
adminedit.php, Metadata section shows :
Modèle d’appareil: insta360 oners
Titre de l’image: IMG_20230914_162848_00_492.insp
Date et heure de la prise de vue: 09/15/2023 16:46
Date et heure originale de la prise de vue: 09/14/2023 16:28
IMG_20230914_162848_00_492.insp is the name that replaces the title, in french only, english and german titiles are emptied.
Description, tags, codeblocks are kept (no change.)
Only some titles.
Only in my VR album. VR cameras (insta )
Encoding problem ? metadata from my camera ?
I do not know.
If I erase all exif data in my localhost VR album images,
Then I replace those images online,
will I keep my titles, description, or will zenphoto think they are new images ?

Hm, did/can you look at the metadata titles of these albums? Do they store anything unusal as the title?
Maybe try to refresh the metadata on one problematic image manually and see what happens then.
Also please look at Options > Image > Metadata refresh behaviour there you can generally prevent updates on title+description or all metadata (as tags could be involved, too). That had been added quite a while ago as you might want to refresh without loosing the main fields usually edited manually after importing.
I still don't know why this should be updated via setup run… I could only imagine some file/folder permission issues and problems to read images somehow so they are always re-read.

As long as you directly overwrite the files with the same named files Zenphoto should not consider them new because they are already in the database. To be on the sure side do this step by step. Just in case…
Also be sure to close your site for visitors during that as there is always a tiny moment the image is missing and if someone or bot catches that it might fail.
I did try the Metadata refresh utility on my localhost machine : I loose the same titles
I always manually enter new titles with the edit page
Those titles were also lost when O2switch upgraded the version of Mysqli needing a Zenphoto setup.
I do not use Metadata.
Maybe I need to deactivate the metadata plugin.
How can I do this ?
If it is requested by Zenphoto, I should not loose the titles I have manually entered
here is an image :

The title was :

After metadata plugin action (or runing setup), french title became
charset = Ascii {"info":{"gyro_stabilized":false,"initial_view_changed":false}}
No english and no german title.
Here is a metadata from an image that does not change the title :

There is no title in this Metadata !
The Metadata utility did not change that title !
This answer is a bit long, but I think my camera gives wrong metadata titles !
Those titles were also lost when O2switch upgraded the version of Mysqli needing a Zenphoto setup.
This should not be happening! MySQLi is just the PHP library handler and not the database itself. But encoding mismatches can always result in "funny" results…

Okay, good to hear that you are sure its not a bug from our side.

That might indeed be or it did store them wrong due to an error (A camera nowadays is just a computer …). We had in the past (more often) that some cameras did some "creative usages" of the more or less existing EXIF/IPTC standards.
We have a process what to use for the title as described here:
https://www.zenphoto.org/news/zenphoto-image-metadata-processing/
But what you see seems really be off… I guess if you edit the file itself and add a proper title it should work.
