Good evening,

I am writing on a plugin. In my local installation it works fine. So I created a revision, and downloaded it using the regular mechanism of the admin area. However, my productive Piwigo keeps telling me the message from the subject.

I was reading forth and back in the docs, double-checked the plugin skeleton and so on, and I am not able to find my mistake.

A pointer to the right chapter of the documentation would be great.

Thanks a lot in advance.

BR,
Peter
