HTTP Error 500 resulting in white page on front end (9 posts)

    Hello great community of wordpressers,

    I'm new here and have been using wordpress but for a couple of months. A website I was about to go live with last night suddenly produces a white screen on the front end - back end still accessible. The error reads http error 500 - rather generic.

    Actions I have taken so far on the advice of this forum and other sources:
    1. Changed the name of the plugins folder (via FTP) to deactivate it.
    2. Ensured all CHMOD permissions are 755
    3. Checked the character encodings for MySQL (via php admin) to ensure they are all UTF-8 and not Latin characters. The reason I suspected the characters is that just before this problem occurred I replaced some text on the home page with accented text in french.

    None of these has worked. The domaine name is
    MsSQL 5.0.9

    Adapted theme - 'Filtered' by Theme Trust

    Any help would be wildly appreciated.

    No I have not - as this has been uninstalled.

    Try reverting to some other theme from your ftp and see if the problem still persist, alternatively you can make wp_debug to true, to see actual errors
    Did you migrate from your localhost to a server ?

    I have done all development on the web server so no migration needed.

    wp-debug - do I activate this in the backend or via phpAdmin?

    I shall do as you suggest regarding another theme and see if the problem persists.

    wp_debug is a function in your wp-config.php
    it is false by default

    Thank you Robin and Chris for your excellent advice and reference links.

    I have found the solution - it was an error of manipulation on my behalf. Unwittingly I overwrote the index.php of the site with the index.php from the theme.

    Had I not gone through the steps you outlined I still would be pulling my hair out - so a profound 'Merci' .
