MLP 2.4.0: Fatal error (only backend) after update

[tyrann0us]

Version information

• WordPress: 4.5.2
• MultilingualPress: 2.4.0
• PHP: 5.3.10 (FastCGI)

Steps to reproduce

1. Update to latest MLP
2. Try to access backend (wp-admin/)

What I expected

Fully functional backend

What happened instead

Error 500 with following error message:
Catchable fatal error: Argument 1 passed to Mlp_Self_Check::remove_mlp_from_update_plugins_transient() must be an instance of stdClass, boolean given in /var/www/vhosts/example.com/httpdocs/wp-content/plugins/multilingual-press/inc/installation/Mlp_Self_Check.php on line 146

What other information/logs to you need?

@tyrann0us thanks, the information was (good) enough.

I already fixed this in the 2.4 branch. You can expect a patch release soon.

For now you could just remove stdClass in the line mentioned in your error message, or temporarily rename the multilingual-press folder (and thus deactivate the plugin), visit the Plugins page in your main site's WordPress Admin, and then undo the renaming, and reactivate MultilingualPress. The reason for the error message is that you don't seem to have ever checked for plugin updates...?

BTW, in order to continue with MultilingualPress, you will have to update PHP to version 5.4+ for the next major release.
