it means you need a text editor with line numbers! Do you use a PC with Windows? Does Notepad+ or whatever it is called allow you to have line numbers? And we might be able to do this a different way.
I was just searching for a fix to this same error
Notice | Uninitialized string offset: 0
Current versions SP 5.1.3 WP 3.4.1
Is this the line you are looking for.
Line 364 from above file
if ($spThisUser->member && is_array($spThisUser->newposts[‘topics’]) && in_array($tidx, $spThisUser->newposts[‘topics’])) $f[$fidx]->topics[$tidx]->unread = 1;
If I should have started a separate thread I apologize.
First, it’s not an error – its a notice and harmless. That said, we still try to get rid of them when they occur. Thought we had removed this one and had multiple confirmations, but will take a closer look at the code again.
