I installed this plugin https://wordpress.org/plugins/wp-gallery-custom-links/ and got an error during install that I didn't have time to read before the page refreshed.
Now my media picker didn't load at all.
I removed the plugin completely with no luck, and now I can't even reach the wp-admin anymore. Getting errors like:

I have downloaded a fresh copy of wordpress and replaced the wp-admin folder, the wp-includes folder, wp-config.php file, wp-login.php file.
I have tried changing name on the plugins folder, still does not work, I have tried removing my theme to be able to reach the wp-admin, but still doesnt work.
I suspect it might be the database, but i'm out of luck to find the issue.. Can anyone help ?
I've been across this issue several times, as said by Vaviloff, a space is placed in the beginning of the file (before <?php) is the thing your looking for.
Some possible reasons :
Possible solutions :
<?php EDIT : I just saw you can't reach wp-admin. That's tricky, but I've had the same problem some times. And well, it was an intrusion (due to an obsolete plugin).
What did I do ?
