# Requirements

Your server needs to be configured with at least:

* php 8.1 or newer
* MySQL 5.0 or newer(\*)
* Apache 2.2 or NGINX (recommended)
* The following php extensions enabled on php.ini
  * pdo
  * pdo\_mysql
  * mbstring
  * gettext
  * fileinfo
  * gd2
  * xml
  * zip
* cURL extension is recommended

(\*) If you are using version 8.x or newer, please set the authentication method of your database so it uses the MySQL native password. The default method (caching\_sha2\_password) will not work. Thanks to user jellevdbos for pointing this out.

If possible, make sure to have php configured with:

* memory\_limit set to 128M or more
* post\_max\_size set to 128M or more

If files fail to upload, even small ones, try adding these lines to your config file (includes/sys.config.php) at the top.

```
@ini_set( 'upload_max_size' , '256M' );
@ini_set( 'post_max_size', '256M');
@ini_set( 'max_execution_time', '300' );
```
