On my install of Piwigo 16 that has been upgraded from 15.7.0 I get shown error messages on the Photo sizes configuration page in the admin when I click on the "show details" link. Rather than showing a default size like the others, 3XL and 4XL show:

Code:

Warning: Undefined array key "w" in /var/www/html/piwigo/_data/templates_c/p6jhns_623in6^fa71c34bb4571b77bce065cdd09509d343282728_0.file_configuration_sizes.tpl.php on line 243

I have never modified any of the image size settings but this installation is being used for testing so it did pass through 16.0.0RC2 and 16.0.0RC3 between 15.7.0 and the release version of 16.0.0. (This instance is running on PHP 8.4.11)

On my other testing site (which is running PHP 7.4.33 in case that matters) which is a fresh install of 16.0.0 those two image sizes display blank sizes ("x pixels") rather than the error messages.

I do not meet this issue with my test site which has this environment :
Piwigo 16.0.0
Système d'exploitation: Linux (container)
PHP: 8.3.28
MySQL: 8.0.36
Bibliothèque graphique: External ImageMagick 6.9.11-60

I switched instance 2 (the one that had a fresh install a few days ago) to PHP 8.4 and it showed the same error as my other test instance (that was already on PHP 8.4). (I also tried to deactivate all the plugins but the error showed the same either way.)

Activating the reset to default values link resolved the error on this install but since this was a fresh install in which these values had not been touched I am assuming that somehow I was missing something from the installation process.

I must have made some kind of error in the process of doing both of the previous installs. I did another fresh install (PHP 7.4.33) and this one is now fine with regard to the missing dimensions. I don't understand what went wrong before. Sorry about that.

Moberley, maybe you can mark the thread as solved ?

moberley · 2025-11-30 17:32:02

I apologize I didn't know where that option was.

After upgrade from Piwigo 15.7.0 to Piwigo 16.1.0 I have the same (probably) problem with Image Sizes configuration page. PHP crashed on this page with no output (blank page). I have PHP logs switched off for the moment, tomorrow I will try to get some error messages and provide details.
All other configuration pages work fine.

Piwigo 16.1.0

See [Github] Piwigo issue #2488 it's resolved in the upcoming version 16.2.0 :-) we're waiting for a few more bugs to be fixed to release this new version.

Thanks! That's not critical for me, will wait 16.2.0

Merry Christmas for everybody!
