i created a website on an ISP by FTPing my drupal folder. the site worked fine for a day, then it began to display junk characters on all pages. (http://benegal.org/drupal). so then i created a sub-domain and ftp'ed again. this worked fine for a day and then garbled characters again (http://kalki.benegal.org). It seems if i either rename the themes folder to something else, it starts working.
Now what i do is to change the default theme, and the site works (for this i have to type ?q=admin/themes in the URL, and login again). Then the garbled characters stop. (If even _this_ page comes garbled, then the only option is to rename themes to OLDTHEMES, and then rename it back.
Can anyone tell me how to stop this, and whats going on anyway. on my local machine, the site works fine.
