I use a child theme for most of the layout of my web page. After installing the new Pro theme, I noticed that when I tried to make adjustments to my child theme CSS file, they would not take effect in any browser (Safari, Chrome, Firefox, iOS). I checked my FTP server and my File Manager and the CSS changes were showing there. But when I opened the page in a browser, no changes.
I went so far as to delete the stylesheet entirely. In the appearance > themes section of Wordpress, Wordpress gives me an error that there is no stylesheet attached to the childtheme. When I check the FTP server and File manager, no stylesheet is showing. But all the browsers keep referring to the file. I note the browsers are referring to a stylesheet that ends in style.css?ver=1.2.3. I am not sure what this is referring to but it seems to be some old version of the CSS file which I cannot access
In speaking with my hosting company, they seem to think that this is something to do with the Pro theme. From your standpoint, does that make sense?
