Looks like you need to reupload album_cat_select_body.tpl to your yoursite.com/yourforum/templates/yourtemplate/admin/album_cat_select_body.tpl
Or did you recently do any changes to the file?(album_cat_select_body.tpl )
EDIT: Well also, what version of phpbbxs are you using?
those files exist. I haven't done any change, i have just installed it.
the problem is for all album links in ACP:
Template->make_filename(): Error - template file not found: ADM_TPLalbum_config_body_extended.tpl
Template->make_filename(): Error - template file not found: ADM_TPLalbum_cat_body.tpl
Template->make_filename(): Error - template file not found: ADM_TPLalbum_cat_select_body.tpl
Template->make_filename(): Error - template file not found: ADM_TPLalbum_personal_body.tpl
I use phpBB XS 2 2.0.2.2
