Thanks Doc. I read your other post about sudden changes = host. I think you are right.
The odd thing is it effects every site that I have. I can show you 100% of the time as soon as I get my admin password working and then initiate email, my password quits. As long as I dont attempt email my password will work.
I can recreate this as often as I like.
I noticed that even the new 1.39a release is still using an ancient phpmailer. Why hasnt that been upgraded?
I saw in another thread that I have not found again, that someone else reported the exact same symptoms. ie loss of password immediately after attempted email.
I think this is not a hack nor a server issue but more likely some incompatibility with latest version of php.
IMHO.
