I have the same issue. I was running an old version of WordPress, on a server running an older version of php. I triggered a password reminder and bam – I got this message and can’t log in to my blog.
I contacted my host who transferred the site and the database over to a server running My SQL version 5, but now what do I do?
I’m not sure what I have to change in order to get the site to access the new database rather than the old one. At the moment I am still getting the same error message I presume becasue I need to make some changes.
Please can someone help as I have very little technical knowledge and my hosting company aren’t that familiar with WordPress (or they dont want to help!).
ANy help would be very much appreciated. Many thanks.
