Thanks. The link worked. Love the product.
I’m not sure which issue fixed the problem. I deleted css-javascript-toolbox folder. I also deactivated all plugins and cleaned out the .htaccess files that one of the security plugins created. After that was done I was able to install the CSS & Javascript Toolbox. I am going to reinstall and reactivate my plugins. If you do not hear back from me it means everything works.
I have the same issue with mine. I have deactivated all other plugins and I still cannot get this one to install.
