I guess you have translated the error and original error message could be read as - Failed to enable browser caching for folder "css/".
Please correct me if I differ, however if this is the case then the step taken by user in this thread - Failure to enable browser cache issue should resolve your query.
Let me know if that works or we will investigate further.
actually, the error message is exactly as it was - I have Muse running in German, but I think you are right in your assumption that it is the same as "failed to enable browser caching for...".
I contacted support yesterday because I thought that this message pointed to the cause for my changes not going live. Support was great - turns out that the problem was in no way related to the messages I received after my FTP uploads. I could have taken care of the problem on my own (felt rather stupid), but I was mentally blocked by those messages and thought the cause was to be found there.
I was so relieved that the changes to the site were now going live that I forgot to ask what to do about the four messages (which, during the process of finding my core problem, I was told were "just" messages, not "error messages").
I read the thread you suggested. There are, however, no messages relating to files missing or anything of the sort when visiting the site, so I have decided to let the issue lie for the time being.
Thank you for taking the time to answer my query!
Cheers from Germany
That is totally perfect, so far the site is live and accessible no need to invest extra effort just for a warning message.
However, keep monitoring the site and let us know if you still face any further issues.
