There shouldn’t be any problems with deactivating EDD unless your theme somehow requires EDD.
The best thing to do would be to enable Debug: https://codex.wordpress.org/Debugging_in_WordPress
Basically go in via SFTP to you wp-config.php file and add this line:
define('WP_DEBUG', true);
That will then give you an error instead of a white page and you’ll see what the source of the problem is. My suspicion is that EDD is not fully deleted. I’d also go into your plugin folder (via SFTP) and check whether the EDD plugin folder is still there and delete it completely as well as any other EDD extensions that you had enabled as well.
You should also hit up the EDD support folks as well.
Ok, looks like I am stuck with that plugin. no error showed. the theme doesn’t need it. I had the theme before using it. It even takes down wp-admin.
Email me at support@givewp.com and we’ll sort it out. I’ll have to get back to you on it first thing in the morning, but there’s no reason why that should be happening, at least not because of our plugin.
It turned out it was a hhvm issue and not a plugin issue.
Thanks for the update. Glad you figured it out!
