WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

I didn't know this site exists. So, I asked it on WebApps

I didn't get a solution still. :-(


I am unable to install any theme/plugin to my WordPress 3.0

Downloading install package from http://downloads.wordpress.org/plugin/contact-form-7.2.3.1.zip…    
Unpacking the package…    
Installing the plugin…    
Could not copy file. /public_html/blog/wp-content/plugins/contact-form-7/languages/wpcf7-lt_LT.po    
Plugin install failed.

I get similar messages everytime. Is there any solution?

It's either the configuration of the path where WordPress is installed (you don't have the right path setup) or if the path is correct, you don't have got enough permissions to modify the file system.

So as this answer is very broad, that's because it is of a very technical nature that is bound to your concrete hosting environment. Please contact your hosting support and figure out together with them which path and permission settings are needed for your WordPress installation.

In case you copied over your blog from another system, please reset the path related configuration constants and options. Check your wp-config.php if you make any specific settings in there.

This looks like a server configuration issue. If it's not a path issue on your site (I agree with hakre, this is my first guess) then it could be a CHMOD problem with your folder and file permissions. If the server running WordPress doesn't have permission to modify or edit your wp-content/plugins folder, you will get multiple "unable to create file" errors every time.
