As for the error randomly appearing I can't see any reason for this happening, can you create a new file on your server called phpinfo.php and inside it put this code
Code:
PHP Code:
<?php
phpinfo();
?>
upload it to your server and link me to it, I want to take a look at the configuration to see if there is anything I can find that could possibly be causing this.
Would like to send you a PM about that, but the PM-module in this forum seems as if it is not working.
I have sent a test-message from a test-admin to a test-user and replied it from there back to the admin. All worked fine including the "new message"-alert in the users account (where this function was activated).
But then I could only delete the test message that was sent from the admin-account. I could not delete the reply-inbox-message from the admin-account nor could I delete both (outbox and inbox) in the users-account, though in all cases "message deleted" was shown. So only the one message is deleted, the others remain in their boxes, I have tried it several times in both accounts, every time it tells me that the messages are deleted, but they stay there. Very strange ...
Maybe you could get into that?
BTW, on the server is running PHP 4.4.8, according to the output of phpinfo.
