WordPress 3.7.1 and jQuery.BlockUI Version problem

The error message “blockUI requires jQuery v1.2.3 or later! You are using v1.10.2” cropped on my WordPress site a few months ago when using the backside admin functions. I turned off all plugins and finally found that the problem plugin was Woocommerce. I read every post I could find discussing a fix for the problem and followed all suggestions. I commented out the “alert. . .” line I found in two .js files as suggested and it worked . . . with one little problem. The message no longer shows up on MY computer when accessing Woocommerce functions in the admin panel but it still shows up on my wife’s computer when she uses the same functions. We are both on the same network (in our home) and are logging in to the same WordPress admin panel. I thought about cookies but (as far as I know) I deleted all cookies. Any suggestions?
