A blank WordPress dashboard can be caused by so many things. The common problem is because of:
- Wrong code on your theme
- Installing an uncompatible plugin
To recover an error caused by that, you can simply login into your FTP and change its folder name. Or in other words you are turning off the plugin manually.
But, how if after you do that (via FTP) and the blank screen still exist?
If you do have that problem, please check your plugin. Did you have a plugin such as cache? If you have, do this step:
- Open your wp-config.php and remove the empty space at the bottom
- Add this code to your wp-config (the position doesn’t matter):
Once you do it, you should be able to login into your dashboard. Now, what you have to do is to turn off the cache plugin and remove the addition you did at the wp-config.php
