Me too, i have a lot of wordpress installations for clients so im pulling my hair out at the moment because i cant do anything with all the sites since updating to 3.9 surely WordPress are working on a fix, i hope so anyway…
I have tried everything and i cannot get this to work at all, any help would be much appreciated as i have been looking for something like this for ages, cheers…
Im having the same problem, everytime i try to update i get this error message :
PHP Warning: touch() [function.touch]: Utime failed: No error in D:\CustomerData\webspaces\webspace_00164839\webapps\SiteApp36409\htdocs\wp-admin\includes\file.php on line 179
