PHP 8 & Joomla 4.2.2 issue

[attis119]

Hi,
As PHP 7.4 is getting to its EOL, on a sandbox site I tried to change to PHP 8. After that warnings started to show up:

Warning: Undefined array key "view" in /home/......../lscache/components/com_sppagebuilder.php on line 17
Warning: Cannot modify header information - headers already sent by (output started at /home/......../lscache/components/com_sppagebuilder.php:17) in /home/........lscache/lscachebase.php on line 211

SP Pagebuilder is Pro 4.0.3
After falling back to PHP 7.4 warnings vanished.
Could you please have a look?

Hi
Meanwhile I added isset function to line 17 in com_sppagebuilder.php

17	if ( isset ($this->plugin->pageElements['view'] ))
18	{
19	      if($this->plugin->pageElements['view']!='page'){
20                $this->plugin->pageCachable = false;
21            }
22           else{
23               $link = JUri::getInstance()->getQuery();
24               if(!empty($link)){
25               }
26           }
27        }

Warnings disapperad, tested with SPPB Free 3.8.8 and Pro 4.0.3.
J4 LScache plugin seems to be working on PHP 8 with SPPB this way, but please check if this is a final solution.

I love that you actually posted the solution. It's such a shame that this was months ago and the issue is still left open with no reply.
