It used to be good, not is just annoying

Was a good caching plugin until he added a stupid pop-up in admin area that bags for a back-link a subscription and so on, and the annoying part is that it pops up everytime you move to a diffrent setting tab and you have to close it time and time again because save & close button only works for the current tab. So uninstalled and moved to WP Super Cache is just as fast, does what i need to and I’m not force to see a stupid pop-up every time i need to set something up. Enjoy your pop-ups.
