Saving custom output content in edit module popup

Hi I recently started using Module Manager CK but I'm having trouble with one of the features:

Whenever I try to save changes I've made in the edit module popup (custom HTML module), the changes won't get saved in the database. I've included images to explain my issue.






I'm using the module manager CK plugin for Joomla 2.5

Thanks in advance!

Hi
if you try with another module, does it work? Is it just a problem into the custom html module ?
CEd

It doensn't work with other modules either. For instance: if I try to edit and save 'Basic Options' within a menu module it won't get saved as well. Actually, any option i try to edit and save within a module will not be saved so far.

I'm using Chrome as my browser by the way.

which version of joomla are you using ? 2.5.X ?
please try with firefox and tell me

I've tried it with firefox but still no succes. I've also tried it with 2 different websites, but still nothing . These are the system informations of the 2 websites:

Can you otherwise tell me what version of joomla and wich browser you are using that will get it to work properly?
