Thanks a lot for your interest in this plugin. We will check this issue and will get back to you as early as possible.
Thanks a lot for your patience. We have investigated this issue and haven’t found any conflict. What is happening is that shortpixel plugin adds a new admin column on the media library page. As the available space is limited here, the width of the columns gets decreased to accommodate all of the available admin columns.
Our suggestion is you can remove any admin columns from the viewport that is not necessary for you. You can do this by clicking on the “screen options” from the top right corner of the media library page and then uncheck the columns that you want to remove and finally click on the “Apply” button. Here is a screenshot
Thanks a lot again. Have a nice day.
We’re marking this ticket as resolved and will be happy if you have any other questions or concerns!
