Additional Pages, without any specific change but a review, is not marked as compatible with Piwigo 2.4.

Sadly it appears that Advanced Metadata and Grum plugins aren't working either - since no further development seems to be taking place with these, any thoughts for another method to gain access to the Photoshop:keywords and LR:hierarchical keywords fields so I can display my full hierarchy for keywords on the info panel?

Also, Stripped theme doesn't work.. :(
