I already tried doing memory=128MB solution but it did not work. site and wp-admin both given same error.
I'm not really sure what else to try. Help?
This is what I do when encounter this kind of problems.
1.Turn WP_DEBUG as true in your wp-config.php
2.Using default theme to see if the site is ok or not.
3.Deactivate all plugin to see if the site is ok or not.
4.Activate the plugins one by one to see if the site is ok or not.
Most of time, you can find which theme or plugin break your site when you go through this process.
