Activation Error

[weswitt]

i'm running piwigo version 13.4.0 and current version of openstreetmap plugin.

when activating the plugin i get an error that says "an error occurred". the plugin displays a map as expected but changing the plugin settings have NO effect. for example, changing the "map height" has no effect. so it seems that there is in fact some kind of error preventing the plugin from working properly.

Same issue. Fresh install of the Piwigo 14.2.0
PHP: 8.2.10
MySQL: 10.11.6

nginx logs shows this error:

Solution:
change the owner to "www user" of the piwigo folder. Enough not recursively. Ubuntu nginx user is www-data:
chown www-data:www-data piwigo
