Blank Page - Install Impossible


I tried to install YOURLS on my Debian 10 Server but it failed.
PHP 7.3

I have a blank page when i click on the install button. is empty, even with debug mode activated.
In the console i have nothing except : “** dataslayer: injecting Launch monitors **”

Could you help ?


The browser console will not give information about server error. See

I gave everything i add, even if i know the console doesn’t give information about server error.
But the debug mode give me nothing also.
So i don’t know what to do.

Did you check server logs ?

It seems there is an issue with the connection with the database

That’s strange because the database exist. I will recheck the typo

What could be wrong ?

/** The name of the database for YOURLS */
define( 'YOURLS_DB_NAME', 'database' );

 ** If using a non standard port, specify it like 'hostname:port', eg. 'localhost:9999' or '' */
define( 'YOURLS_DB_HOST', 'localhost' );

/** MySQL tables prefix */
define( 'YOURLS_DB_PREFIX', 'yourls_' );

 ** Site options

/** YOURLS installation URL -- all lowercase, no trailing slash at the end.
 ** If you define it to "http://sho.rt", don't use "http://www.sho.rt" in your browser (and vice-versa) */
define( 'YOURLS_SITE', '' );

Anything could be wrong:

  • mysql server not running
  • mysql server not reachable on that host and/or port
  • … ?

I installed Wordpress, Drupal, Forum CMS on it without issue.
First time it happens.

Ok, error found. YOURLS doesn’t support UTF8MB4 format.
So i recreate a new database with only UTF8

Current dev version of YOURLS is all utf8mb4
