Hi. Answering for my client, here.
0) The server has not, as far as we know, changed recently. The tech people there (at Jusssolution) say it’s nothing they know of.
1) The EE Wizard reports “yes” to every item. So that’s clear.
2) The site is up and running currently, and works well for other site visitors, and for other site editors on other computers.
I will ask my client to report what browsers and versions he is using; he reports this happens with more than one browser.
Perhaps it’s an IP address issue? But in that case, wouldn’t it ask him to login again?
TTFN
