PHP errors

[hcgreier]

Hi,

installed it, but I get 2 errors after reloading the wiki:

[urlpath]\lib\plugins\popupviewer\syntax\viewer.php on line 45
[urlpath]\lib\plugins\popupviewer\syntax\viewer.php on line 62

When reloading the page, the errors go away, but no external site is loaded into the popup.
This was tested on a localhost Apache with PHP v8.2, wiki with "Jack Jackrum".

Must the wiki run on an online server for the popup to work?

Thx,
hc
