Hello i have in my WordPress site 2 differnet custom plugins.
Both Plugins have the meta box libary directly included.

The first Plugin is a half year old (include a old metabox version) and the second plugin new developed (has the new metabox version included).

The problem now, wordpress load the plugin with the old metabox version at first.
So the new second plugin use and load the old metabox version also (but it need the new version).

How can be avoid this problem?
I can't update the metabox in the first old plugin 🙁

I included the Libary with following tutorial:
https://metabox.io/docs/include-meta-box-plugin-themes/

Thank you very much

Hi,

Currently, our loader mechanism couldn't detect which version is older and decide to load the newer one :(. It's probably better to load the plugin from the wordpress.org with the help of TGM Activation class.

Is it possible to destroy the Metabox Class or add namespaces?
So that i only use the one metabox libary with is included in the plugin?

Thank you

You can prevent Meta Box from loading by defining the constant RWMB_VER. Then you might need to manually load the library like this:
```
require_once 'path-to-meta-box/inc/loader.php';
$loader = new RWMB_Loader;
$loader->init();
```

Hello this is my situation:

Plugin 1 (need Metabox 4.7.1):
```
define( 'RWMB_VER', '4.7.1' ); // Example
require_once 'plugin-1/path-to-meta-box/inc/loader.php';
$loader = new RWMB_Loader;
$loader->init();
```
Plugin 2 (need Metabox 4.9.8):
```
define( 'RWMB_VER', '4.9.8' ); // Example
require_once 'plugin-2/path-to-meta-box/inc/loader.php';
$loader = new RWMB_Loader;
$loader->init();
```
But this can not work because the class RWMB_Loader already exists.

Thank you very much

You can defined the constant RWMB_VER in the wp-config.php file. That makes both plugins won't load Meta Box.

Then in the 2nd plugin, where you can edit, add the following lines:
```
require_once 'path-to-meta-box/inc/loader.php';
    $loader = new RWMB_Loader;
    $loader->init();
```

Ok i understand, but
Plugin 1 have to load Metabox 4.7.1 and
Plugin 2 have to load Metabox 4.9.8.

Plugin 1 is not compatible with Metabox 4.9.8 and
Plugin 2 is not compatible with Version 4.7.1

The only possible way is with namespaces or?

Thank you very much

You can't load 2 versions of the plugin. The best thing you can do is edit the plugins to compatible with 1 specific version.
