I'm noticing quite a few bugs in my upgrade from 1.9.7 to 2.2. I'm pretty sure I followed the instructions correctly, but it occurred to me that I never did an md5 checksum on the downloaded file. Is that obsolete? I don't seem to find instructions or the appropriate checksum file anywhere.
This is not a criticism. I'm trying to figure out how to be sure that the file I downloaded and then uploaded again to my webhost is intact. If it isn't, that could be the source of the bugs I am seeing. This used to be done by checking an md5checksum file. I'm not sure that's still the way it is done.
Let me know.
