Hi - attached to this I have found the uploaded pictures in the backend as you told me......everything seems to be OK.
But I think I have found the reason:
I have deleted the installed version: CB Gallery Plugin (ps_cbgallery_2.4.0+build.2019.05.15.16.28.42.6277da0b1) and installed an older version ob the CB Gallery: ps_cbgallery_2.4.0+build.2019.03.08.14.30.33.0670077ad ....and this worked!!!, the moderator was able to approve the pictures as expected....as soon as I upgrade to the newest version (ps_cbgallery_2.4.0+build.2019.05.15.16.28.42.6277da0b1) I get the issues as described......can you verify this?
