Hi all,

I was just congratulating myself on recreating my lost (local) Joomla site after a hard disk failure and a corrupt backup, when K2 suddenly started displaying the following error when I try to use it at all:

Notice: Undefined offset: 1 in I:\xampp7\htdocs\plugins\system\k2\k2.php on line 702

Looking at the offending line 702:

$getK2CacheHeaders = json_decode(trim($getK2CacheHeaders[1]));

Not sure what this line does, but it's the "1" in square brackets which K2 is objecting to apparently.

Can anybody tell me what the problem is and how to fix it? I'd be very grateful.

Joomla 3.9.19

Many thanks!

Stay safe

Andy.

Many thanks Fotis, as always: I shall give that a go. All the best.

I have the same problem but this is a first time install using the latest release. (d4tm.org). It's also adding a large gap after JM Slideshow. v2.10.4 (dev) fixed.
