I am new here, so I apologize if this is stupid or already answered. I recently inherited a Wordpress site from a client, the developer is long gone, never to be heard from again. Groan. I moved all the files from his GoDaddy Account to the corporate GoDaddy account and transferred the domain. The Launch screen works fine. It has a button which is pointing to a login screen (http://corcexpo.info/wp-login.php). It then prompts user for Login credentials. When I click the Login button: a blank white page appears (http://corcexpo.info/wp-admin/).
Any thoughts? We are using the exact same domain name, we didn’t implement https or anything like that. I just assumed it would all transfer and work like magic without any more work on my end. Because I am in the DEEP end here (I have other mad skills). 
Can't login after moving wordpress site to a new GoDaddy account
If you are getting sent to /wp-admin/ after logging in as admin, then it doesn’t sound like your problem is anything to do with s2Member. That is as expected.
The white screen of death in WordPress can have several causes. The most common are having spaces or lines before the opening <?php tag or after the closing ?> tag on a PHP file, or running out of memory.
If you have edited a file recently, then the former is probably the cause here. You should re-trace your steps and check.
Here is how to fix the memory issue.
I would not even know how to edit a PHP file. I have only worked on free templates in Wordpress, so I am totally green here. I know nothing. I can’t imagine that I have a memory problem. Having worked at Apple for five years, I am pretty savvy on the computer memory issues. And I have none. But I really appreciate that you are pointing me in the right direction. White Screen Of Death. I love it. So I posted a job on Upwork, because there is NO way that I can solve this issue. I suspect a Wordpress person could solve this inside of 5 minutes, because I modified nothing. Well, that’s not exactly, true. I had to modify wp-config to enter the password for my new SQL database that I had to create when I transferred everything. Then I imported the old SQL database into the new one. It should work. It doesn’t. I am hosed.
I see now that you were talking about some memory issue within Wordpress. Not my Mac. If I didn’t have an issue yesterday, why would I have an issue today? I was modifying the website when it was on the other GoDaddy account/server. Now I moved it, result: WSOD.
Disliking them as much as I do, I would say that that’s GoDaddy for you. They are a real PITA when it comes to dealing with WordPress. If you can recognize when a rep is talking nonsense – some of the GoDaddy reps are awful, but some are much better – your best bet is actually to call them and explain the issue.
Right on. I totally agree. However, the dude that I had was SUPER helpful and really competent. So I am reaching back out to him. I am beginning to think this is a THEME issue.
Thanks again!
I would have guessed a theme if this problem were on the front-end, but I am not sure about the back-end. But you can test your guess by using an FTP client or cPanel’s File Manager to just re-name your theme’s folder. That will automatically deactivate it and cause a default theme to be used instead.
@jacannon: Ask admins to look in the “error_log file”, they know what this means, this is where errors of the WEB server are saved. White screen problems should be seen there, but not always…
Fantastic! Much thanks!!!
Great advice. Where is the Theme folder located?
This is what I see in my Theme folder:
zBench
twentytwelve
twentyten
twentyeleven
This is what I found:
12-May-2017 19:22:22 UTC] PHP Fatal error: Cannot redeclare url_shorten() (previously declared in /home/corcadmin/public_html/wp-includes/formatting.php:5291) in /home/corcadmin/public_html/wp-admin/includes/misc.php on line 267
Try renaming zBench to zBench-old. The other themes are all defaults, so they won’t be causing this problem.
Update WP folders “wp-admin” and “wp-includes” by FTP. Download the latest version of WP, unpack, delete these folders from the server and upload them again. The problem seems is there, maybe corrupted files.
