Hi,
I had that Illegal offset problem in my new blog, and the solution posted by Whooami solved it.
you open wp-includes/cache.php
you locate line 125, which reads:
if (isset ($this->cache[$group][$id])) {
and immediately before that line, you paste this in:
if (!is_string($id) || !is_numeric($id)) {
return false;
}
Only thing I had to do beside pasting it before line 125 was pasting it also right before line 285, as the error ocurred in two lines.
Thanks a lot for your help!
