The problem was indeed in my sendpic.php file, but i had nothing to do with that log file.
in the original sendpic.php the code starts like this;
<?php/*
SENDPIC Imagevue Mod
v0.4
[+] config: sendemail_subj (if not set - default used)
[?] html email fix?
I just changed that to:
<?php
/*
SENDPIC Imagevue Mod
v0.4
[+] config: sendemail_subj (if not set - default used)
[?] html email fix?
So just let the comment start at a new line and everything works fine. Perhaps some strange settings on the server (i'm with Site5.com)? Otherwise i found a bug
To answer your question about that logging-line to comment out; Right now, i use the log, and i know how to create a new file etc;...
But if i was a "stupid" user and i didn't want to log everything (what most users won't do) i think its better to disable this option by default. The few people who may want to use the logging option, will find how to uncomment this line!
