Try adding
define('WP_TEMP_DIR',ABSPATH.'wp-content/uploads/'); to your wp-config file. The install cannot find a temp directory.
I’ll test it on a development copy of the site, thanks for the suggestion!
If this is the root of the issue though, it would strike me as a bit strange – the install not being able to find a temp directory.
Well I’ll be damned. That works as a workaround. Cheers kmessinger!
I am curious though. I did test with the team’s plugin installed to check compatibility with automatic updates, and it gave a pass across the board.
Any ideas as to where this issue comes from? Or how to prevent it in the future?
I think the server does not have write/read for the wp-content folder.
You just defined a path to a folder that has write/read privileges.
Hm, well I did check for that, and the permissions do check out for the wp-content folder.
Strange. I did make sure to revert to default htaccess files as well, prior to the update, so it can’t be related to that either.
I don’t know about servers but I think it is not only permissions but who owns the server – the server or the application. But again I am way out in left field. Maybe someone will jump in here.
Well, let’s hope so 🙂
By the way, thank you for the tip – I tested it on another site which gave the same installation failure error, it is a solid workaround. I just wish there were a way to drill down to the heart of the matter 😛
Especially now with automatic updates as a feature, it’s a bit uncomfortable not having a real idea of what caused this. Going over some forums, it seems I’ve not been the only one thusfar.
I’ll keep puzzling, just in case.
Similar problem here. I finally did a manual update, but then I’d still get the “server error” page when I went to the update page, just to check.
Reverted to older version. Then inserted the line of code that kmessinger suggested. That worked!
BUT, back at 3.7.1, I still cannot get to update page from admin panel. Server error. Not only that, but image upload from my desktop directly into a post is broken. I now have to upload to the media library first.
AND, on top of THAT, when I do go through these hoops and put up a post, the next page is another server error page. The post will usually go up, but I get the error page anyway.
is anybody else having these issues?
Thanks. I am losing much of this day to what I had thought would be a very quick automatic update to 3.7.1.
I’m having a similar problem. (“permission denied … Cannot update file …Installation failed.”)
But my problem is worsened by the fact that I’m a newbie to WordPress and am clueless when it comes to code or editing. (I’ve recently converted from the now-defunct iWeb, where my ignorance was bliss.)
Reading several forums, I understand that I need to change some code somewhere, but I’m not too embarrassed to say that I don’t know how to do that.
Even reading WordPress’ own troubleshooting page, it appears to sound simple … Yet, here I am.
Is there no “newbie-approved” solution for fixing this error? (Is learning to code the only way to solve problems in WordPress?)
