Thanks, what do you mean by page source? The URL ?If you get the unexpected DB error message, view the page source for a more specific message.
Could this be caused if some other customers upgade to 1.5.x or this is irrelevant?If it's the "too many connections" error you mentioned, that's again a server limit. This time, it's not a per user limit but a global server limit. (And thus may be caused by others on the same server.)
Thank you very much, i will do next time.Right click, select 'View page source'.
Ok, i understand.It's irrelevant, it's a server limit and just depends on the total number of visitors across all sites on the server.
