I already tried doing the php.ini memory=20MB solution but it did not work. I uploaded it under the wp-admin/ folder.
I'm not really sure what else to try. Help?
The memory bump doesn't go into an .htaccess file in wp-admin. It goes into the .htaccess in web root. Use FTP to find and delete the .htaccess file you put in wp-admin.
Then forget about .htaccess files and try adding the line below near the top of your wp-config.php file, a few lines after the opening
Renaming plugin directory temporary solved the problem for me
