Product images on category page became smaller

[vintaya]

Hello,

 

I have a problem with product images on category pages.

I don't know when exactly it happened but the product images on category pages are now smaller than they used to be. 

Here is the long to one of my category pages:

Here is the link to the screen with my back office umages settings:

Below are three things I did recently which may/may not help to resolve my problem:

1. What I had done was to install the new theme on top of existing one. I didn't like the new theme thoug and reinstalled the old one. I regenerated the thumbnails afterwards but there is no change. 
2. Can this be the issue of installing OLARK chat on my shop? Can the chat module narrow my category section?
3. I also migrated my store within my serwer.

 

Please help.

 

Thanks in advance
