Am thinking that XOOPS could do with a test page that a user can go to if they are having problems accessing a feature of the site.

This page would run some tests and shows results to the user. These results could be pasted into a support request.

Similar to these .. http://gemal.dk/browserspy/basic.html but XOOPS specific items such as writing/reading session cookies, referrer information received etc.

Sometimes I get a user who can't log in from home but work is ok and this could show where the problem might be.

Which things would need to be checked?

Search for browsercheck (or browser check) from dave lerner

ah brilliant! Found it.. http://dave-l.com/grafix/index.php?page=bcheck

exactly what I wanted. Thanks Hervet and Dave.

Something like this would be good in the core, like a mini test suite for admins and users to check local and server environments.

I learn something new every day

Thanks for the pointer, Hervé
