can’t change the theme of the blog

Did you upload them through your WP dashboard? You can just go to Themes, Add New, Upload. Your upload should be a zip file. If you would rather do it through Filezilla you just drag your theme (the unzipped folder) over to your themes folder in the wp-content folder. You have to be doing something wrong for all of them not to work.

when i’m uploading it through filezilla it’s not showing it in the dashboard and when i’m trying to upload it through the dashboard it says : Unable to create directory /www/zzl.org/d/i/g/digitalfun/htdocs/wp-content/uploads. Is its parent directory writable by the server?

please ?

Did you upload the themes via FTP into your wp-content/themes directory?

You can’t upload via the dashboard because your wp-content folder doesn’t have the correct permissions.

yes, i uploaded it right to wp-content/themes directory

here is a screenshot of my themes folder : https://img297.imageshack.us/img297/3535/presentation1v.jpg

The files you uploaded with FTP.

Did you download the Theme files then just upload the EXACT same file to your site or did you do anything to the downloaded Theme file?

Most Theme files come zipped into a neat package when you download them. You must unzip or extract the files from inside the file you downloaded. This will give you many more files and much of the time several more directories. One problem with Windows systems is it allows you to look inside the Zipped download as if it was a regular directory. Did the uploaded Theme files still have the funny little zipper symbol on it? Or did you do the unzip or extract step before the Theme was uploaded to your site?

If you mouse over the file you uploaded does it say “Compressed (Zipped) Folder,” does it show a size of the folder under the “Size” Collumn? Or does it just say “Folder Theme xyz” with a size that is only visible when moused over?

WordPress will not recognize a Zipped Theme file as a valid Theme.

i unzipped the files and now when i go to themes it shows few folders(each folder is another theme name) when i enter to each folder it shows many php files etc..

So can you now see the new Themes and change them from your Dashboard?

nope *_*

when i’m trying to upload a theme though the dashboard i’m choosing the zip file and pressing insatll it says : Unable to create directory /www/zzl.org/d/i/g/digitalfun/htdocs/wp-content/uploads. Is its parent directory writable by the server?

You need to change the permissions on your wp-content directory to 755 at least to be able to upload through your dashboard.

and how do i change the permissions ?
