# Problem with theme preview

 * For some reason, I can’t seem to preview themes from my dashboard. I click on
   the theme, but the only option that appears is “activate” – there’s nothing popping
   up to show a preview. The only theme that has a preview is the one that I’m currently
   using. I also have a theme preview plugin, but when I type the supposed URL for
   the preview, nothing shows up. Any ideas?

 * I can’t preview certain themes like amazing-grace and blue-grace, while others
   are distorted with different background and font colors.

 * I have the same problem as Layofflist, I wonder why support isn’t answering these
   inquiries. Also, this problem started after I updated to 2.7.1.

 * Ditto. Same problem. JUST installed 2.7 and could see theme previews. Installed
   2.7.1 about a half hour later and BAM! No preview!

 * The bug is in the file `wp-includes/theme.php`. There are two places in that 
   file where you can find this string:
    `'|[^a-z0-9_.-/]|i'` To fix this problem,
   change both of them to: `'|[^a-z0-9_./-]|i'` (The only difference is the location
   of the hyphen character).

 * I’ve got the same problems, dont worry though it wont affect the performance 
   of the actual theme when you activate it.

 * Uploaded a picture to my site, which does’nt show up either. But the comments
   I wrote to it shows. It made me think of my themes: I think the actual problem
   is that the images that go with the thems don’t show. (And yes, the images folders
   are in the right places: /public_html/xxxxx/wp-content/themes/dark-smoke/)
 * I guess the problem with the themes has something to do with showing/uploading
   pictures.
 * Any ideas…?
