Users encounter "Permission denied" issues. Is there a workaround to solve "Failed to load cache" stacktrace?

I found this in the configuration in xwiki.cfg

I assume xwiki.store.cache.pageexistcapacity=10000 is the default value above ?

#-# Maximum number of documents to keep in the cache.
#-# The default is 500.
# xwiki.store.cache.capacity=500

#-# Maximum number of documents to keep in the cache indicating if a document exist.
#-# Since this cache contain only boolean it can be very big without taking much memory.
#-# The default is 10000.
# xwiki.store.cache.pageexistcapacity=10000

No, no, these are not at all the same caches (there are lots of caches in XWiki ).

The setting for the security cache is in file:

WEB-INF/cache/infinispan/config.xml

in your XWiki installation.

And you need to add in there something like this:

     <local-cache name="platform.security.authorization.cache" statistics="true">
        <memory>
          <object size="100000"/>
        </memory>
     </local-cache>

at the end, just before the closing tag </cache-container> , next to the other local caches.

Of course, you need to restart the wiki after making this change.
