Ok, I will check this out. Does that mean that also the visitors of my website will not see instantly out changes or does this only affect the admins?
Thanks a lot for your help :)
Yes, I am using the WP Super Cache. Should I deactivate this plugin?
Well, on other browsers it seems like it does not have the same issue, although I have to mention that I don’t use them as often as Google Chrome on which I am constantly online because I am logged in as an admin. So, I am not 100% sure if this happens on other browsers too.
