Admin filter not working anymore

[bonsaiko]

Hello,

I installed a plugin and after that, the filter in the admin / catalog page is not working anymore. 

Before that I was able to filter the products to display for example only active products, or products containing a given string in the name, etc.

But now it's not possible anymore.

I contacted the developper but got no news.

Anyone could help me solve this issue ?

The plugin is related to combinations and virtual products.

I noticed that this plugin registers a hook that is called in the prestashop function used to filter the products. I guess it's related but I don't know what to do, except uninstall the plugin, but I can't as I need it...
