Augmenter la dimension des fichiers WP
To increase the file upload size limit in WordPress, you can follow these steps:
Access your WordPress installation via FTP or a file manager provided by your web hosting service.
Locate the wp-config.php file in the root directory of your WordPress installation.
Open the wp-config.php file in a text editor.
Add the following line of code to the file, preferably just before the line that says "/ That's all, stop editing! Happy blogging. /":
define('WP_MEMORY_LIMIT', '64M');
Replace '64M' with the maximum file size limit you want to set.
Save the wp-config.php file and upload it back to your server, if necessary.
After following these steps, the file upload size limit in WordPress should be increased to the value you specified.
