Since updating a couple of my sites to 2.81 I am having trouble inserting images, getting a 'file not writeable' error, even though it definitely is.
Thought it might be random, but it happened again with another site, this time with nextgen gallery, and also with permalinks. This site says the .htaccess is not writeable, which it is.
Tried searching but don't seem to find an answer. Ideas?
