No WP login possible after clean in CCleaner Help Requests Posted June 29 - CCleaner is a very powerful tool. When you use the program for the first time then I would recommend to untick ALL boxes and then step by step tick more and more boxes and see how your system reponds after each step. - The default setting is that cleaning / removing of all cookies is enabled. - Just untick all the "Cookie" boxes for all browsers that show up in the list (Chrome, Edge, ............... ). Log-in for those programs / applications (again). After running CCleaner once more the cookies should be still there. - CCleaner also allows you to select which cookies must be kept and which can be removed. (Options > Cookies).
