Could there be a problem with 7.5 not publishing updated files or actually all new files? I had to use FileZilla to get all my files on my server as 7.5 would not work for me in uploading newly created stacks. Went back to 7.3x
I just had a look and the text-transform CSS is not making it to the page.
So either there is;
a publishing issue (the update is not being published) - can you export and ftp the site to find out?
a cache issue ( the server is not serving the new content) - are you using cloud flair or similar?
the CSS change is not being implemented for some reason - this seems unlikley if you can see the change in RW preview.
I just tried a test with RW 7.5 and this CSS snippet was successfully uploaded and worked as expected when the CSS was in the site-wide code, as well as when I put the CSS in the page inspector code box.
So it appears that this is not a universal problem related to the version 7.5 update.
Thanks for all your assistance. I uploaded to my live folder on my server and it seemed to work. Not sure why it wouldn’t work within my test folder. I did check and there were no duplicate pages, i.e. one html and one php
