i found it cannot upload files ,what can i do to fix it?,the error is :

This suggest DefaultUniqueDocumentReferenceGenerator is not cleaning its cache when it’s unloaded as it should. This kind of issue is generally fixed by restarting XWiki.
i do not think it can be fix by just restart xwiki,i think it is a bug
1.i created a subwiki “s” in xwiki
2.i install file managager application in main wiki and subwiki “s”
3.i upload a file in main wiki’s filemanager,it is ok
4.i upload a file to subwiki “s” filemanager,it is not ok
5.if i restart xwiki
if i upload a file to subwiki “s” filemanager ,it is ok,but if i continue to upload a file to main wiki’s file manager, it is broken
which means ,i can use only one filemanager,the others cannot use
i test it on xwiki11.0.3，it is ok。so there shouble be something happened between 11.0.3 and 11.4
Indeed if you installed the API on several wikis you will have issues. To fix this you should use “Install on farm” for the API part.
how to “Install on farm” for the API part？ any help document is helpful！！
In the Extensions administrations, switch to “installed extensions”, search the filemanager API and next to “Uninstall” button you have an arrow which open a submenu.
thanks alot，i will try
i solved the problem,thanks alot
