A post with no content, only a subject and maybe a poll gets this error if you try to edit it. Line 42 of post.php likely needs a small change by adding an "if size>0" type statement. My php is rusty, but from my php help file:

Quote:

fread() reads up to length bytes from the file pointer referenced by handle. Reading stops when length bytes have been read, EOF (end of file) is reached, or (for network streams) when a packet becomes available, whichever comes first. <?php // get contents of a file into a string $filename = "/usr/local/something.txt"; $handle = fopen($filename, "r"); $contents = fread($handle, filesize($filename)); fclose($handle); ?>

The above sample to avoid similar problem might be changed to:

Quote:

<?php // get contents of a file into a string $filename = "/usr/local/something.txt"; $handle = fopen($filename, "r"); $readsize = filesize($filename); if ($readsize>0) { $contents = fread($handle, filesize($filename)); } else { $contents = ""; } fclose($handle); ?>

A change similar in style to this to line 42 of post.php may get rid of first warning.

Some other minor tweak to line 42 may get rid of second warning, hard to say exactly without seeing source code, but one option is to fake having something if nothing, eg

Quote:

else { contents="X"; }

rather than

Quote:

else { contents=""; }

{Mod edit: fixed quote}
