 * I just had WordPress installed by the host for me (he is very nice isn`t he?).
   I try to customise it, and, i started with downloading some basic themes, simply
   because i cannot code myself yet. I can only edit. I have already edited one 
   theme to get a custom look, but this time, EVERY single theme gives me an error
   message. Only the default and the classic theme seem to work ok.
 * Here are the error messages i get:
    Fatal error: Call to undefined function is_tag()
   in /www/hostbot.com/c/a/s/cassel/htdocs/blog/wp-content/themes/green-light.1.03/
   green-light/index.php on line 24
 * or

    Fatal error: Call to undefined function
   the_title_attribute() in /www/hostbot.com/c/a/s/cassel/htdocs/blog/wp-content/
   themes/l2aelba-1/index.php on line 16
 * or
 * Fatal error: Call to undefined function the_tags() in /www/hostbot.com/c/a/s/
   cassel/htdocs/blog/wp-content/themes/red-car-theme/index.php on line 23
 * No matter what theme i try to install, i always seem to have an error pointing
   to a tag function. Any idea what i did wrong? Or if there is one corrupt file
   somewhere?
 * Thank you.

 * Are you using widgets and if so are your themes able to use widgets?

 * All the themes i picked are identified as widget ready but i dont know if i am
   using any. In the basic wordpress to edit the use of widgets, i dont have any
   placed on the sidebar. However, if i try to move any one of them, then i get 
   an even messier page as the bottom half of the page is completely missing.
 * Another thing that i noticed is that i cannot post more than one post. I tried
   to see if posting 2 or 3 messages would lower the error message, but in fact,
   only one could show up. Not sure if it help pinpointing to the problem.
 * Thanks
