Trying to update s2member pro. The developers gave me the license key but not the user name.
Is there a way to update with just the license key?
Pro update issue
Hi Sherry.
You’d use your username from s2member.com, the one you used when you created the account there.
I tried to find your account with the details you used here in the forum, but couldn’t find it. I guess you used something different.
You can also download s2Member Pro from your Account page and update it manually, if you can’t get the Dashboard updater to work with your credentials. https://s2member.com/account/
Let me know if that helps. 
Hello again! I don’t have an account in my name. I have s2member Pro that was installed by a developer that used their own name to purchase the license. I have the user name and key to use when there are updates that require me to input this information.
I just updated my website and now it is having issues loading. I get 504 errors. I contacted Dreamhost support who pointed me to s2member as the culprit.
Tech support response: This is happening because the theme or a plugin is adding these rules to the HTTP headers:
expires: Wed, 11 Jan 1984 05:00:00 GMT
cache-control: no-cache, must-revalidate, max-age=0
It looks like it could be the plugin s2member-pro, you can test this by toggling the plugin off and using our Proxy Cache plugin as explained
here: https://help.dreamhost.com/hc/en-us/articles/215300647
If I disable s2member my website has a critical error.
Can you help me with this?

I am going to restore to a point before the lates update for s2member and see if that changes what is going on. I can’t disable the plugin. I have disabled most of the other plugins trying to see if any of those are causing this issue, but so far nothing changes.
Hi Sherry.
Could you tell me the username you’re using to update Pro?
About the problem you’re having, did it start with the update or where you having it before too? What version did you have before? It seems you have version 200301 now, is that the one before the update or an earlier one?
The new release doesn’t touch anything related to caching, so I doubt it’s the culprit. What exactly made your host suspect s2Member?
What error do you get when you disable s2Member? Did you deactivate just Pro or the Framework?
You can also ask your webhost if it could possibly be related to Mod Security… https://s2member.com/kb-article/mod-security-odd-403-503-500-errors/
