I am setting up http://www.bvcr.org I installed wordpress through the host admin and was setting up plugins trying to see which I would need to to make the site how I wanted it
I insa\talled oEmbed for BuddyPress and and I got an error that was something like 'no header for this script' try to go back to the site and got my first 500 internal server error I decided to do a fresh install
This happened another 2 times both with different plugins sorry I ca not rememner the second 2 that did it I was up very late trying to get the site going.. All I remember is they where plugins for buddypress and media/video
After the thrid time I came here and did a search and found that people who had had this problem solved it by
a} deleting the pluginh though FTP I deleted the plugin but did not work so I deleted all the plugins
b) deleting the .htaccess did this this did ot work
What can I do to find out what is causing the problem to a. sort it now b. stop it happening in the future
