EDIT Sorry for this post - i've found out the solution. I had to get my member to re-create her signature. She had some odd characters in there before. -------- Hi, I just moved my forum to a new host. One of my members reported recieving the following error: Notice: unserialize() [function.unserialize]: Error at offset 54 of 134 bytes in /home/.pilar/vbunet/thevbushow.com/forums/extensions/Signatures/default.php on line 74 ===================================== default.php code is as follows ======================================= <?php /* Extension Name: Signatures Extension Url: sirnot@gmail.com Description: Enables each user to have a small, one-line signature.
