Error message: The plugin does not have a valid header.

Hi, I had the same problem with Simple Crumbs plugin.

The problem was in the top lines of code of the simplecrumbs.php

Originally it had an @ in front of every line so all I had to do was REMOVE @ from beginning of each line. See example below.

Hope this will solve your problem as well.

Original code
/*
@plugin Name: Simple Crumbs
@description: Simple Crumbs – Generates a breadcrumb trail for pages and blog entries. Requires use of permalinks, and php > 4.1.0, tested WP 2.7
@note: link/crumb information from $query_string
@note: page/post information from $post
@note: using permalink info for making links
@note: using permalink structure for bootstrapping unrolled recursions (deepest to topmost)

Thank you!

My issue ended up being my mixup on which files went into which folders. I had originally uploaded the free program then bought the licenced version. There was a matter of some files that needed to be deleted and some that needed to be overwritten.

Anyways, yesterday, after trying to get it to work for two days, I got the right folders into their correct folders and got it to work.

This morning, I got a reply from the developer which told me basically to do things the way I did.

But your response is very appreciated. Sometimes this stuff is complicated, and sometimes it’s really simple. But if you don’t know what you’re doing, you don’t know which one it is.

Thanks!
