Dear all,
everything works perfectly apart the sitemap link analysis.
When I start it the window with the progress bar opens.
It starts running with the green progress bar.
After a while the progress bar become red.

The window says:
"Sitemap is being generated and analyzed, please don't close the page until completion.
Open a new tab to continue navigation.
Error storing XML file in the analyzer cache folder,
please check permissions and try again"

com_jmap/cache as +xw permissions so it would be able to create new files and, if needed, folders.

Is there any other cache or temporary folder where jmap is writing in?
