Hmmm. the MSM build listed on the Edit Sites page is “Version: 2.0 Build: 20101215” even though I’ve updated the new files (with Build: 20101220) by following the instructions here: http://ellislab.com/expressionengine/user-guide/cp/sites/install.html Is there a step I’m missing other than replacing those 3 files?
I have a main site which has no problems uploading, 1 other MSM site in another domain for which upload doesn’t work anymore. We also have 6 sites in temporary subdomains that we are testing, 1 of which has no problems uploading as well, the rest do. To rule out permission issues i have created upload destinations to a folder which does work on the main site, and the 1 subdomain site, using the exact same settings, but no luck.
When I try to upload an image I get a “upload_unable_to_write_file” error message both in the Publish Modal window and in the File Manager.
I did do a version update.
