Yes, i testesd it now.
I used total clean installation of WP - 3.5.1 and latest version of Overwrite Uploads - 1.0.2 plugin.
All other plugins was disabled.
The theme is default Twenty Twelve.
No other settings are used.
I added necessary code in file.php, checked it twice.
And the results are:
1. The message: "Overwrite Uploads requires a new filter to be added to WordPress. If this is a new installation or you recently upgraded WordPress, please see the installation instructions on the Installation page for information on adding it." is permanent on top and not disapear even if you add new hooks???
2. On Drop files here (media-new.php) when upload files i recive error:
Fatal error: Call to a member function get() on a non-object in #######\wordpress3\wp-includes\cache.php on line 113 on each file uploaded?
3. If you put file with same name it not re-uploaded it just copied with new name with digit after name. So the plugin not working not Overwrite the existing files?
Whats to do next?
