file_put_contents, failed to open stream: Permission denied

[leoqiuwr]

I am using php 5.4 and IIS 8.0 for a website.
There is following warning message on all the webpages except homepage:
------
Warning:file_put_contents(mydomain.com\httpdocs\attachments\.htaccess): failed to open stream: Permission denied in mydomain.com\httpdocs\libraries\joomla\filesystem\file.php on line 421
------

And the content in the .\attachments\.htaccess is below:
order deny,allow
deny from all

How can I fix the problem.
Thanks.

You can fix the problem by giving write permissions to Apache on that file. The question is, however, which extension is trying to write to that file?

Thanks, itoctopus.

I tried to set full control to the file .\libraries\joomla\filesystem\file.php and the directories.
But It doesn't work.

[itoctopus]

I meant the .htaccess file.

Thank you, itoctopus.
The problem has been solved. It is due to the wrong permissions to the directories.

Just in case anyone else comes across this thread in Google: I just encountered this issue, and installed the mpm-itk Apache module to fix it.
