Ok, a short while ago I had some (much appreciated) assistance regarding me getting 500 errors. I wasn't too fussed at the time about this, being more concerned about fixing the actual errors, but the 500 errors were also saying something along the lines of:
"additionally, a 500 error was encountered trying to use a custom error document"
Or words to that effect.
I'm wondering if anyone knows what may be causing this, as my other error documents work fine (atleast, I know my 404 and 401 work fine), and are listed in my .htaccess as:
ErrorDocument 400 /400page.php
ErrorDocument 401 /401page.php
ErrorDocument 403 /403page.php
ErrorDocument 404 /404page.php
ErrorDocument 500 /500page.php
