Nagios Support Forum

Fresh install, all tests passed on the install.php page. When I remove it, I get this below which should be the localhost ping chart. Any ideas?

PNP4Nagios Version 0.6.26
Please check the documentation for information about the following error.

Call to undefined function simplexml_load_file()

Already fixed that one with
apt install php7.2-xml

Then fixed this error:
application/models/data.php [979]:

Ubuntu 18.04 php 7.2

solution:
edit
if(sizeof($pages) > 0 ){
to
if(is_array($pages) && sizeof($pages) > 0 ){

Hope this helps someone else. Thanks for the great forum!

Hi @jesseg,

Hope this helps someone else. Thanks for the great forum!

Thanks for following up with the solution! Did you have any other questions or shall I lock this one up?

Close it, thanks! Edit was to fix typo in the word array.
