Can't log in to admin

probably not hacked
ftp to site or use host’s file manager to rename plugins folder, thus deactivating all plugins
if a plugin is borked this will let you log in

if this doesn’t help, rename your theme folder, thus activating default theme
if a theme error this will let you log in

if neither of these work, try these memory options

1. Try adding this line to your wp-config.php file:
define('WP_MEMORY_LIMIT', '128M');

2. If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 32M try 128M:
memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)

3. If you don't have access to PHP.ini try adding this to an .htaccess file:
php_value memory_limit 128M

Thanks for this, Samuel. Unfortunately, none of these steps helped. (I couldn’t find the PHP.ini file so assume that I don’t have access.)

While trying those things, I remembered something that may be the cause of the problem! Last week, in Dreamweaver, I began to synchronize all files. Usually I omit the blog files but I forgot this time. I aborted the exercise when I realized it was doing the blog, too. This must be the root of my problem. Any idea of how to fix it?

I have to go out of town today, but I’ll check back tonight.
Thanks again.

I still can’t get in — get blank page when I click on “Site Admin”. Any other ideas? Please help!
