Hi, Everybody is good
I install XWiki 12.10.5 with tomcat 9, PostgreSQL 13.2 and java 9.0.4. when deleting an attachment I get NullPointerException:
XWiki “xwiki.cfg” Storage config:
xwiki.store.recyclebin.content.hint=file
xwiki.store.attachment.hint=file
xwiki.store.attachment.versioning.hint=file
xwiki.store.attachment.recyclebin.content.hint=file
xwiki.recyclebin=0
storage.attachment.recyclebin=0
xwiki.store.versioning=1
xwiki.store.attachment.versioning=0
I hope to get your help, thank you.
